Looking for the best Shopify bundle app? Here is the short version, then the full breakdown below.
The quick answer: For most stores, Oxify Quantity Breaks is the best Shopify bundle app in 2026.

Kaching Bundles has a 5.0 star rating from 4,370 reviews. Want a strong free plan to test the waters? AOV.ai, BOGOS, and Bundler all start free.

How we ranked these apps
We did not just count stars. 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 complaints pulled from 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 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 on bundling: always sell the items on their own too. When the only way to buy is the bundle, sales can drop. 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 12 best Shopify bundle apps in 2026
1. Oxify Quantity Breaks (Best overall)
- Rating: 4.9 ★ (10 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 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
- 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 review count is small 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 ★ (4,370 reviews), Built for Shopify
- Price: Free to install, with a free trial. Paid usage applies as your bundle sales grow.
- 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: The “free to install” label can grow into a real bill as your bundle revenue rises. Check the pricing tiers before you scale.
3. BOGOS: Free Gift Bundle Upsell (Best for promotions)
- Rating: 5.0 ★ (3,500+ reviews), Built for Shopify
- Price: Free plan available, then paid tiers.
- 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: With so many offer types, the dashboard can feel busy when you first set it up.
4. Pumper Bundles Quantity Breaks (Best for quantity breaks)
- Rating: 4.9 ★ (2,718 reviews), Built for Shopify
- Price: Free plan available, then paid tiers.
- 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 ★ (2,400+ reviews), Built for Shopify (listed as “FBP, Fast Bundle Product”)
- Price: Free to install, with paid usage as you grow.
- Best for: Stores that want a wide range of bundle formats.
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: 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 ★ (2,000+ reviews), Built for Shopify
- Price: Free plan available, with low-cost paid plans.
- 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 Upsell (Best genuinely free app)
- Rating: 5.0 ★ (1,186 reviews), Built for Shopify
- Price: Free.
- Best for: Stores that want a capable bundle builder without a monthly fee.
AOV.ai stands out because it is fully free while still carrying the Built for Shopify badge.
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 Builder & Upsell (Best modern builder)
- Rating: 5.0 ★ (1,025 reviews), Built for Shopify
- Price: Free to install, with paid usage as you grow.
- Best for: Stores that want a clean, modern bundle builder plus upsells.

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: 4.9 ★ (678 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.

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 on this list, and recent reviews include real complaints about bugs and surprise charges. 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.

- Rating: N/A (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.
Key features:

How bundle apps charge you
Pricing is where stores get surprised, so read this before you install.
There are two common models:
- Set monthly fee by store size: You pay a fixed amount or a small set of tiers. Example: Simple Bundles ($14 to $149).
- Free to start, then scales with bundle revenue: The app costs nothing until your bundles earn a set amount, then bills based on the extra revenue they make. Examples: Oxify Quantity Breaks (free until $500/month, then $9.99 to $149.99), Kaching, Fast Bundle, and Rapi.
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.
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, or the bundle can feel like a trap.
- 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.
