12 Best Bundle Apps for Shopify in 2026 (Ranked & Verified)
Looking for the best bundle app for Shopify? The honest answer depends on your use case — so that is how this guide is organized.
Quick answer, by use case:
- Best overall (quantity breaks, BYOB, and cart offers in one): Oxify Quantity Breaks & BYOB
- Best free bundle app: AOV.ai Bundles Quantity Breaks (entirely free); Bundler has the best classic free tier
- Best for inventory tracking and 3PL fulfillment: Simple Bundles & Kits
- Best for mix and match / Build Your Own Box: Oxify, or Rapi for the most polished builder
- Best for Black Friday and volume discounts: Oxify or Pumper
- Best for Shopify Plus: Simple Bundles & Kits, with BOGOS for POS and headless
- Biggest review base: Kaching Bundles (5.0 ★, 5,418 reviews)
- Best native (free, but limited): Shopify Bundles — read its limits below before relying on it
If you landed here because Shopify's native Bundles app frustrated you — separate inventory tracking, the three-options-per-bundle cap, missing discounts — jump straight to the alternatives to the Shopify Bundles app section. Everything on this page links to the full Shopify bundle app breakdown below it.
Why bother with bundles? They are one of the simplest ways to grow average order value (AOV). A 2022 case study by Swanky, a Shopify Plus agency, found that adding a bundle builder to baby brand DockATot's store drove a 55% jump in AOV and an 86% rise in revenue per user — and 72% of bundle-builder sessions ended with an add to cart, roughly 30% above the product-page average. That is more money from the same traffic.

Full disclosure: Oxify is our app
This blog is published by Oxify, the maker of Oxify Quantity Breaks & BYOB — the app ranked first below. We are not neutral, so judge the method, not the motives: every rating, review count, price, and free-plan limit on this page was read from the live App Store listing in August 2026 (most recently re-checked August 31, 2026), every one of the 12 apps gets a specific watch-out (including ours), and we say plainly when a rival is the better choice. Two examples: if a large review base is your main trust signal, pick Kaching Bundles (5.0 ★, 5,418 reviews) over Oxify's much smaller 12-review base. If you ship through a 3PL or ERP, pick Simple Bundles & Kits — its SKU splitting beats ours.
Cart-transform vs variant-based bundles: the thing nobody explains
Before comparing apps, understand the one technical difference that causes most bundle headaches — and most of the Reddit complaints about Shopify's native app.
- Variant-based bundles create a new product (or variant) that represents the bundle. Simple to set up, but the bundle now has its own inventory count, separate from its components — which is why merchants find themselves overselling or manually syncing stock. It also eats into Shopify's variant limits fast: two products with a few sizes and colors each can blow past what a bundle product can hold.
- Cart-transform bundles (built on Shopify's Cart Transform API) keep the component products as-is. The app combines them in the cart at the moment of purchase, so inventory decrements against the real SKUs automatically, discounts apply without codes, and there is no phantom "bundle product" to maintain.
Shopify's native Bundles app is variant-based, which explains its two most-cited complaints: bundles that track inventory separately from components, and the cap of three options per bundle (about 100 variant combinations). Modern apps like Oxify use cart transformation, and operations-focused apps like Simple Bundles & Kits go further by splitting each bundle order back into individual SKUs for your 3PL or ERP. If a listing does not say how it handles inventory, ask support before you install — it is the difference between a bundle that runs itself and one you babysit.

How we ranked these apps
What we verified, and when: in August 2026 (most recently August 31) we opened all 12 live App Store listings and recorded each app's rating, review count, pricing tiers, free-plan limits, and Built for Shopify status. Those are the numbers in the table above and in every section below — the same figure reads identically everywhere on this page. What we did not do: run lab speed benchmarks. Where we talk about performance, we lean on the requirements of Shopify's Built for Shopify program, and we say so.
The ranking is not a star-count contest. Each app was judged on what actually matters when you sell:
- Feature depth. How many bundle types it supports, and whether it includes a real bundle builder.
- Verified pricing. Confirmed on the live listing, including how the price scales as you grow.
- Live rating and review count. Pulled from the current App Store page, not old blog posts.
- Where it shows. Does the offer appear on the product page and in the cart, where buyers decide?
- Speed and theme safety. Does it carry the "Built for Shopify" badge and use theme app blocks?
- Inventory sync. Does it break a bundle into single SKUs for clean fulfillment?
- Setup ease. Can a non-coder launch it in one sitting?
- Honest watch-outs. Real complaint themes pulled from each app's recent reviews.
Why use a bundle app at all?
Here is the problem. Your product page sells one item at a time. There is no "buy 2, save 10%." No reason for a shopper to grab a second thing. That is money lost on almost every order.
A bundle app fixes that. It gives shoppers a clear reason to add more.
What a strong bundle app does for you:
- Raises AOV. The Swanky/DockATot case above is one proof point. One merchant review on the Oxify listing (Go Ayurveda Dhanvantri) reported a 25% AOV lift after switching it on.
- Clears slow stock. Pair a slow seller with a hot one.
- Cuts your app bill. A good bundle app can replace two or three separate tools.
- Keeps your store fast. The best ones use Shopify theme blocks, not messy code.
One tip backed by Harvard Business School research: always sell the items on their own too. Studying Nintendo's console-and-game bundles, Derdenger and Kumar found that mixed bundling — the bundle plus standalone options — clearly beat pure bundling: when products could only be bought together, revenue fell by roughly 20%. The single option makes the bundle feel like a smart choice, not a forced one.
Want the deeper "why" behind bundle pricing? Shopify covers it in their own product bundling guide, and we break down the numbers in our bundle pricing strategy post.
Bundle types, explained simply
Pick the bundle type that fits how people already buy from you:
- Quantity break: "Buy 3, save 15%." Best for one hero product. (Deep dive here.)
- Mix and match: "Pick any 3 from this collection." Best for variety. (Deep dive here.)
- Build Your Own Box (BYOB): A bundle builder lets the shopper create their own set, step by step. Best for snacks, skincare, and gifts.
- Fixed bundle: A set group sold as one. Best for starter kits.
- Frequently bought together (FBT): Shows items that pair well. Best for add-ons. (FBT vs bundles, by revenue.)
- BOGO and Buy X Get Y: "Buy one, get one." Best for promos.
The strongest apps support several of these at once, so you are not stuck with one play. The feature matrix after the reviews shows exactly which app covers which format.
The 12 best bundle apps for Shopify in 2026
1. Oxify Quantity Breaks & BYOB (Best overall)
- Rating: 4.8 ★ (12 reviews), Built for Shopify
- Price: Free until your bundles earn $500 a month, then $9.99 to $149.99/mo based on the revenue your bundles generate. You only pay once the app is making you money.
- Best for: Stores that want one app to run every bundle type, including a full bundle builder.

Oxify Quantity Breaks & BYOB is our own app, as disclosed above — and it is our top pick because it is the most complete bundle app on this list. Most rivals do one or two things well. Oxify does the whole job in one place.
Key features:
- A full bundle builder for Build Your Own Box and mix and match
- Quantity breaks and tiered volume pricing on the product page
- Fixed bundles, BOGO, and Buy X Get Y, auto-applied at checkout with no codes
- Free gifts and subscription pricing in the same widget
- A cart progress bar and free shipping triggers to nudge bigger carts
- A/B testing, campaign scheduling, exclusions, and a revenue analytics dashboard
- Cart-transform discounts, so component SKUs keep their real inventory counts — no separate bundle stock to babysit
- Pairs natively with Oxify Cart Drawer & Upsells, so the same offers follow the shopper into a slide cart
- Theme-friendly, no-code setup that works with any Shopify theme
That breadth means it can replace three or four separate tools. And because it is Built for Shopify, it meets Shopify's top bar for speed, design, and integration.
The pricing is built around return on investment. You start free and pay nothing until your bundles bring in $500 a month. After that, your plan scales with the revenue your bundles create, so the cost only grows alongside the money the app earns you.
Why it ranks first: the deepest feature set here, a real bundle builder, Built for Shopify quality, and free to start.
Watch out for: Oxify launched in mid-2025, so its 13-review base is tiny next to apps that have run for years. If a huge review base is your main signal of trust, Kaching is the safer pick. On features and quality, Oxify is the most complete option on this list.
2. Kaching Bundles App & Upsells (Best brand trust)
- Rating: 5.0 ★ (5,418 reviews), Built for Shopify
- Price: Free to install with a 7-day free trial. Paid plans run $14.99 (Starter), $29.99 (Scale), and $59.99/mo (Pro).
- Best for: Merchants who want the safety of an app thousands of stores already run.

Kaching is the most reviewed bundle app on Shopify, and the near-perfect score is no accident.
Key features:
- Quantity breaks, product bundles, and volume discounts
- Free gifts and custom upsells
- A/B testing to compare offers
- A revenue analytics dashboard
- Clean, no-code builder that fits most themes
Watch out for: There is no permanently free plan — after the trial, plans run $14.99 to $59.99/mo. And Kaching is focused on deal-style offers rather than a full Build Your Own Box builder. If either is a dealbreaker, see our full Kaching Bundles alternatives guide or the summary section below.
3. BOGOS: Free Gift Bundle Upsell (Best for promotions)
- Rating: 5.0 ★ (4,057 reviews), Built for Shopify
- Price: A 30-order lifetime free plan, then $29.99 to $109.99/mo plus $0.05 for each order beyond your plan's limit.
- Best for: Stores that run lots of gift and promo offers.

BOGOS is the promotion powerhouse, handling almost every gift and discount play from one dashboard.
Key features:
- Free gift with purchase and gift-with-spend rules
- Buy X Get Y and classic BOGO
- Volume discounts and custom bundles
- A bundle builder you can place anywhere on the site
- Works across plan tiers, POS, and headless storefronts
Watch out for: The "free plan" is really a trial: 30 free orders total, ever — not per month. Budget for a paid plan from day one, and factor in the $0.05 per-order overage during promo-heavy months. The dashboard can also feel busy at first with so many offer types.
4. Pumper Bundles Quantity Breaks (Best for quantity breaks)
- Rating: 4.9 ★ (3,239 reviews), Built for Shopify
- Price: Free plan that covers your first $300, plus a 7-day free trial. Paid plans run $9.99 to $49.99/mo.
- Best for: Stores focused on quantity breaks and volume discounts.

Pumper is a popular, conversion-focused app built around "buy more, save more" offers.
Key features:
- Quantity breaks and tiered volume discounts
- Bundle offers and free gift triggers
- Conversion-optimized, customizable widgets
- Product-page placement where buyers decide
- No-code setup
Watch out for: It leans toward quantity and volume plays. If you need deep mix-and-match or 3PL SKU breakdown, look at Oxify or Simple Bundles.
5. Fast Bundle (Most bundle types)
- Rating: 5.0 ★ (3,036 reviews), Built for Shopify (listed as "FBP | Fast Bundle & Upsell")
- Price: No general free plan (free for development stores only). Paid plans run $19 to $139/mo with a 7-day free trial.
- Best for: Stores that want a wide range of bundle formats.

Is Fast Bundle still on the Shopify App Store? Yes — and this trips up other roundups. The original "Fast Bundle Product" listing was removed in mid-2026 and the old URL now returns a 404, which several 2026 articles wrongly report as the app being gone. It was relisted at a new address as FBP | Fast Bundle & Upsell, with its 5.0 ★ rating and 3,036 reviews intact. Checked and current as of August 12, 2026.
Fast Bundle is the "does everything" option, with around eight bundle types.
Key features:
- Fixed bundles, mix and match, and a bundle builder
- Volume discounts, BOGO, and Buy X Get Y
- Product add-ons
- AI "frequently bought together" suggestions from real store data
- AI bundle image generation and a deep design editor (custom CSS and JS)
- Shopify POS support
Watch out for: There is no free plan for live stores, and it leans heavily on the storefront. If you run a 3PL or need automatic SKU breakdown for fulfillment, it is weaker there.
6. Bundler (Best free-friendly pick)
- Rating: 4.9 ★ (2,564 reviews), Built for Shopify
- Price: Free plan available. Paid plans are among the cheapest here: Premium $9.99/mo and Executive $19.99/mo, with a 7-day free trial.
- Best for: Stores that want a simple, proven bundle app and a free starting point.

Bundler keeps things simple, and the free plan already does a lot.
Key features:
- Classic bundles, bundle deals, and quantity breaks
- Mix and match and volume discounts
- Popup bundle display
- Subscription integration for recurring bundles
- No-code, beginner-friendly setup
Watch out for: Lighter reporting and no SKU-level inventory breakdown. It is built for straightforward offers, not complex warehouse logic.
7. AOV.ai Bundles Quantity Breaks (Best genuinely free app)
- Rating: 5.0 ★ (1,508 reviews), Built for Shopify
- Price: Entirely free — no paid tiers at all.
- Best for: Stores that want a capable bundle builder without ever seeing a bill.

AOV.ai stands out because it is fully free while still carrying the Built for Shopify badge. Note the listing was recently renamed from "AOV.ai Bundles Upsell" to "AOV.ai Bundles Quantity Breaks" — same app, same reviews.
Key features:
- Bundle builder for custom and Build Your Own Box offers
- Bundle offers and fixed bundles
- Volume discounts
- Customizable widgets
- No-code setup
Watch out for: A fully free model can mean fewer advanced controls than paid tools. Test whether it covers your exact discount logic.
8. Rapi Bundles & Upsell (Best modern builder)
- Rating: 5.0 ★ (1,358 reviews), Built for Shopify
- Price: Forever Free plan until your bundles generate $100 a month, then Starter $15, Pro $29, and Elite $59/mo, each with a 7-day trial.
- Best for: Stores that want a clean, modern bundle builder plus upsells.

Rapi is a newer, fast-growing app with a polished builder experience — and one of the few here that publishes exact revenue thresholds for every tier, so you know precisely when the bill starts.
Key features:
- Bundle builder and Build Your Own Box
- Volume discounts and quantity breaks
- BOGO and Buy X Get Y deals
- Upsell offers
- No-code, theme-friendly setup
Watch out for: A smaller review base than the veterans, so test it on your theme before a big campaign.
9. Simple Bundles & Kits (Best for fulfillment)
- Rating: 4.8 ★ (740 reviews), Built for Shopify
- Price: Free plan (3 bundles, 50 monthly orders). Paid plans: Basic $14/mo, Grow & Advanced $39/mo, Plus $149/mo.
- Best for: Brands that ship through a 3PL, warehouse, or ERP.
Simple Bundles is the operations choice. When a customer buys a bundle, it splits the order into single SKUs so your stock and fulfillment stay correct.
Key features:
- Automatic SKU-level breakdown for clean fulfillment
- Mix and match, multipacks, and Build Your Own Box
- Subscriptions and B2B bundles
- Bypasses Shopify's variant limit
- Works with ShipStation, Amazon, POS, and review apps
- Bundle analytics
Watch out for: It is built for back-end accuracy more than flashy front-end design. Some features sit on higher tiers.
10. Amplify, formerly PickyStory (Premium AI, with a warning)
- Rating: 4.5 ★ (525 reviews)
- Price: Premium paid plans.
- Best for: Bigger stores that want AI bundles plus cart and post-purchase upsells in one premium tool.

This app (recently rebranded from PickyStory to "Amplify, Bundles & Upsell") blends AI-driven bundles with cart upsells and one-click post-purchase upsells.
Key features:
- AI-personalized bundle and upsell offers
- Pre-purchase bundles plus in-cart offers
- One-click post-purchase upsells
- A visual builder for shop-the-look style bundles
Watch out for: Its 4.5 rating is the lowest of any paid app on this list, and the recurring theme in recent negative reviews is billing — surprise charges and bugs. Test it carefully and watch your monthly bill before you commit.
11. Rebolt (Bundles plus upsells on a budget)
- Rating: 4.8 ★ (555 reviews)
- Price: Free plan, with an Advanced plan around $14.49/mo.
- Best for: Stores that want Amplify's mix of bundles and upsells for less money.

Rebolt blends bundles and upsells in one affordable app.
Key features:
- Build Your Own Box and mix and match
- Fixed bundles and combo bundles
- Frequently bought together and volume discounts
- Popup bundles
- Analytics, plus support for page builders and side-cart apps
Watch out for: A smaller install base than the leaders, so test it on your theme first.
12. Shopify Bundles (Free and native)
- Rating: 2.8 ★ (543 reviews), built by Shopify
- Price: Free.
- Best for: A first fixed bundle when you have zero budget.
The native app is free and made by Shopify — but its 2.8-star rating is the lowest on this list, and it tells you how far "fixed bundles only" gets most stores.
Key features:
- Fixed bundles and multipacks
- Real-time inventory tracking inside Shopify
- No coding required
Watch out for: No mix and match, no volume discounts, no analytics — and two structural limits drive most of its one-star reviews. First, it is variant-based: the bundle is its own product, so merchants report inventory that tracks separately from the components and images that do not carry over. Second, the cap of three options per bundle (roughly 100 variant combinations) rules out many multi-variant catalogs. Most growing stores outgrow it fast — see the alternatives section right below.
Alternatives to the Shopify Bundles app
If you searched for "alternatives to the Shopify Bundles app," it is almost always for one of these four reasons — here is the fix for each:
- Inventory tracks separately from components. Pick a cart-transform app (Oxify) so stock decrements against real SKUs, or Simple Bundles & Kits if you also need each order split into component SKUs for a 3PL or ERP.
- The three-options / ~100-variant cap. Simple Bundles explicitly bypasses the variant limit; Oxify and Fast Bundle handle multi-variant mix and match without creating a variant explosion.
- No discounts or quantity breaks. The native app builds kits but not "buy 2, save 10%." Oxify, Kaching, and Pumper all put tiered discounts on the product page and apply them automatically at checkout.
- You want it free. AOV.ai Bundles Quantity Breaks is entirely free and far more capable; Bundler's free tier is the classic budget pick.
Which bundle types does each app support?
No other roundup puts this side by side, so here it is: the eight bundle formats that matter, across all 12 apps.
| Bundle app | Fixed | Mix & match | BYOB builder | Quantity breaks | BOGO / BXGY | Free gift | Subscriptions | SKU split |
|---|---|---|---|---|---|---|---|---|
| Oxify Quantity Breaks & BYOB | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | — |
| Kaching Bundles | ✓ | — | — | ✓ | — | ✓ | — | — |
| BOGOS | ✓ | — | ✓ | ✓ | ✓ | ✓ | — | — |
| Pumper | ✓ | — | — | ✓ | — | ✓ | — | — |
| Fast Bundle | ✓ | ✓ | ✓ | ✓ | ✓ | — | — | — |
| Bundler | ✓ | ✓ | — | ✓ | — | — | ✓ | — |
| AOV.ai Bundles Quantity Breaks | ✓ | — | ✓ | ✓ | — | — | — | — |
| Rapi Bundles & Upsell | — | — | ✓ | ✓ | ✓ | — | — | — |
| Simple Bundles & Kits | ✓ | ✓ | ✓ | — | — | — | ✓ | ✓ |
| Amplify | ✓ | — | — | — | — | — | — | — |
| Rebolt | ✓ | ✓ | ✓ | ✓ | — | — | — | — |
| Shopify Bundles | ✓ | — | — | — | — | — | — | — |
✓ = a core, advertised feature. — = not offered, or not a core feature; confirm on the listing if it is critical to you. "SKU split" means the app breaks a bundle order into its component SKUs so a 3PL, warehouse, or ERP sees the real items. Amplify fits this matrix loosely: its strength is AI-assembled combos plus cart and post-purchase upsells rather than classic bundle formats.
Other bundle apps worth a look
These five did not make the main 12, and unlike everything above, we have not re-verified their listings — so we are deliberately not quoting ratings or prices here. Check the current listing before you install.
- Zoorix: Bundles & Cross Sell. Bundles plus cross-sell with a native cart drawer, AI recommendations, mix and match, and quantity breaks. Good when you want product-page and in-cart offers together.
- Dealeasy, by Logbase. Volume discounts, quantity breaks, tiered pricing, and mix and match, plus a cart progress bar for free shipping and gifts.
- Assortion: Upsell & Bundles. A clean, modern app that puts bundles, upsells, and post-purchase offers in one place.
- FoxSell Bundles. Build-a-box with infinite variants, add-ons, free gifts, and automated inventory sync. Aimed at larger, complex catalogs.
- Koala Bundles. Bundles with a post-purchase upsell focus.
Which bundle app should you choose?
Start with your store stage, then fine-tune with the router below. (For the full decision framework, see how to choose a bundle app for Shopify.)
| Store stage | Best pick | Why | Also consider |
|---|---|---|---|
| First store, little budget | AOV.ai Bundles Quantity Breaks | Entirely free, Built for Shopify, includes a builder | Shopify Bundles for one basic fixed kit |
| Growing store | Oxify Quantity Breaks & BYOB | Every bundle type in one app; free until bundles earn $500/mo | Kaching Bundles for the biggest review base |
| High volume / Shopify Plus | Simple Bundles & Kits | $149/mo Plus tier with SKU-level splitting for 3PL and ERP | BOGOS for POS and headless storefronts |
Now the situation-by-situation router:
- You want the most complete all-in-one app (builder plus every bundle type): Oxify Quantity Breaks & BYOB.
- You want maximum trust and reviews: Kaching Bundles.
- You are focused on quantity breaks and volume discounts: Pumper Bundles Quantity Breaks or Oxify.
- You want a genuinely free app: AOV.ai Bundles Quantity Breaks. (BOGOS's free plan covers just 30 orders lifetime, so treat BOGOS as a paid app.)
- You want the widest set of bundle types: Fast Bundle.
- You ship through a 3PL or warehouse: Simple Bundles & Kits (SKU sync).
- You run constant gift and BOGO promos: BOGOS.
- You are a large store that wants AI plus upsells: Amplify, or Rebolt for less.
- You have zero budget and just need one fixed kit: Shopify Bundles.
Need more detail on a specific situation? The next sections dig into the use cases we get asked about most.
Best Shopify bundle builder apps (Build Your Own Box)
If shoppers should assemble their own set — snack boxes, skincare routines, gift kits — you need a true bundle builder, not just a discount widget. Oxify Quantity Breaks & BYOB includes a full Build Your Own Box builder alongside its other offer types (our mix-and-match bundle apps roundup compares this category in depth), AOV.ai Bundles Quantity Breaks gives you a builder for free, and Rapi has the most polished modern builder experience. If those boxes ship from a warehouse, Simple Bundles pairs its builder with SKU-level order splitting.
Best bundle app for Shopify with volume discounts
Oxify Quantity Breaks & BYOB and Pumper are the strongest volume-discount picks: both put tiered "buy more, save more" pricing directly on the product page, where the buying decision happens. Kaching does the same with the biggest review base, but has no permanently free plan. If volume pricing is your main play, a dedicated quantity breaks app is the cleaner starting point — and our ultimate guide to quantity breaks covers the strategy end to end.
Best bundle app for Shopify with inventory tracking
Simple Bundles & Kits is the clear winner here: it splits every bundle order into individual SKUs, so stock counts, your 3PL, and your ERP all stay accurate. Shopify's native Bundles app also tracks component inventory in real time, but only for fixed bundles. Most storefront-focused bundle apps lean on Shopify's standard inventory sync, so if warehouse accuracy is critical, put SKU breakdown at the top of your checklist — the feature matrix above shows it is rare.
Best product bundle app for Shopify Plus stores
High-volume Plus stores should weigh three things: operations-grade inventory handling, headless and POS support, and how pricing scales. Simple Bundles & Kits is our Plus pick — its dedicated $149/mo Plus tier and SKU-level order splitting are built for the 3PL and ERP workflows most Plus stores run. BOGOS is the alternative when POS and headless storefronts matter more than fulfillment plumbing. And check every app's top pricing tier before a big quarter: Oxify caps at $149.99/mo and Fast Bundle at $139/mo, so a record month will not blow up your bill.
Best free bundle apps for Shopify
"Free plan" means wildly different things across this category, so here are the actual limits, checked August 12, 2026:
| Bundle app | Free plan? | The actual limit | Paid plans |
|---|---|---|---|
| AOV.ai Bundles Quantity Breaks | Yes — entirely free | No paid tiers at all | None |
| Shopify Bundles | Yes | Fixed bundles only, 3 options per bundle | None |
| Oxify Quantity Breaks & BYOB | Yes | Free until bundles earn $500/mo | $9.99 to $149.99/mo |
| Rapi Bundles & Upsell | Yes | Free until bundles generate $100/mo | $15 to $59/mo |
| Pumper | Yes | Covers your first $300 in bundle sales | $9.99 to $49.99/mo |
| Simple Bundles & Kits | Yes | 3 bundles, 50 orders per month | $14 to $149/mo |
| Bundler | Yes | Feature-limited free tier | $9.99 to $19.99/mo |
| BOGOS | Barely | 30 free orders — lifetime, not monthly | $29.99 to $109.99/mo + $0.05/extra order |
| Kaching Bundles | No | 7-day free trial only | $14.99 to $59.99/mo |
| Fast Bundle | No | Free for development stores only | $19 to $139/mo |
AOV.ai Bundles Quantity Breaks is the best genuinely free option — no paid tiers at all, 5.0 ★ across 1,508 reviews, and it still carries the Built for Shopify badge. Rapi and Oxify are the strongest "free until it works" picks: nothing to pay until your bundles generate $100 or $500 a month respectively. Shopify's native Bundles app is free too, but its 2.8-star rating shows how quickly stores hit its fixed-bundle ceiling.
Best bundling app for Black Friday on Shopify
For BFCM you want offers you can schedule ahead, test, and trust under load. Oxify Quantity Breaks & BYOB covers that checklist with campaign scheduling, A/B testing, and BOGO plus free-gift offers in one widget; Kaching is the battle-tested pick that thousands of stores already run. Set your bundles up in October, pair them with a countdown timer for urgency, and never install a new bundle app the week of the sale. Our full Black Friday bundle playbook walks through the offer calendar step by step.
Best Kaching Bundles alternatives
Kaching is excellent — a 5.0 rating across 5,418 reviews is hard to argue with — but it has no permanently free plan (free to install with a 7-day trial, then $14.99 to $59.99/mo), and it centers on deal-style offers rather than a full bundle builder. The closest alternatives: Oxify Quantity Breaks & BYOB if you want the same product-page offers plus a Build Your Own Box builder, free until your bundles earn $500 a month; Pumper if you want a near-identical quantity-breaks experience with a free plan; and Bundler if you want the cheapest proven paid plan at $9.99/mo. (Full comparison: Kaching Bundles alternatives.)

How bundle apps charge you
Pricing is where stores get surprised, so read this before you install.
There are two common models:
- Flat monthly fee: a fixed price or a small set of tiers, whatever your bundles earn. Examples: Kaching ($14.99 to $59.99), Simple Bundles ($14 to $149), Fast Bundle ($19 to $139, with no general free plan), and Bundler ($9.99 to $19.99).
- Free to start, then scales with bundle revenue: the app costs nothing until your bundles earn a set amount, then bills based on the revenue they generate. Examples: Oxify Quantity Breaks & BYOB (free until $500/month, then $9.99 to $149.99), Rapi (free until $100/month, then $15 to $59), and Pumper (free plan covers your first $300).
The revenue-based model is friendly when you are starting out, because you pay only once your bundles are already making money. Just check the upper tiers so a strong month does not surprise you — and watch for per-order overages: BOGOS, for example, adds $0.05 for every order beyond your plan's limit, which compounds fast in a promo-heavy month.
Common bundling mistakes (and how to avoid them)
We see the same errors over and over. Skip these and you are ahead of most stores.
- Bundling for you, not the buyer. Group products that solve one problem together, not just whatever you want to clear.
- Discounting too hard. A 40% bundle discount can wipe out your margin. Start at 10 to 15%.
- Hiding the offer. If the deal only shows deep in the cart, few people see it. Put it on the product page too.
- Bundle-only products. Always sell items on their own as well — the Nintendo research above showed roughly 20% less revenue when the bundle was the only option.
- Ignoring your theme. A heavy app can slow your pages. Pick a Built for Shopify app that uses theme blocks. More in our bundle app theme compatibility guide.
How to launch your first bundle
You do not need a developer. Follow these steps:
- Pick one goal. Raise AOV, clear slow stock, or push one hero product. Just one.
- Pick one bundle type that fits that goal.
- Set a safe discount. Start at 10 to 15% so you protect your margin. (See how many tiers to use.)
- Show it where people decide. Put the offer on the product page and inside the cart. In-cart offers convert well because the shopper is already buying.
- Wait two weeks, then read the data. Keep what lifts AOV. Cut what does not.
