Best Shopify Mix and Match Bundle Apps (2026)

Want shoppers to build their own bundle — and spend more doing it? Here are the 10 best Shopify mix-and-match bundle apps for 2026, compared on price, features, and real merchant reviews.

Here’s the short version: Shopify’s free Bundles app cannot do mix and match. Shopify confirms this in its own Help Center — the native app only handles fixed bundles and multipacks. So for a real “pick any 3” or “build your own box” experience, you need a third-party app.

We tested the top options on what actually matters — pricing rules, inventory sync, storefront design, and setup speed — and read the real reviews, not just star counts.

Our 2026 winner is Oxify Quantity Breaks. It bundles mix-and-match, build-a-box, quantity breaks, upsells, and free gifts into one app — all included on a flat $9.99/month plan, the lowest paid entry price of any full-featured app on this list. It carries Shopify’s Built for Shopify badge. Full list and comparison below.

Ratings and pricing are from each app’s live Shopify App Store listing as of May 2026 and can change. Note: some apps are labelled “free to install” on the App Store but only offer a free plan for development stores — the cheapest plan for a live store is shown above. Always confirm on the official listing before installing.

In a hurry? Pick by your situation:

• Want the lowest paid price for a full feature set → Oxify Quantity Breaks
• Want a genuinely free plan to start → Bundler or BOGOS
• Sell in-store and online → Fast Bundle (POS support)
• Ship complex kits, need inventory sync → Simple Bundles & Kits
• Design is your #1 priority → Bundly

What Is a Mix-and-Match Bundle?

A mix-and-match bundle lets a shopper pick the items they want from a set you choose. You set the rules. They fill in the blanks.

Picture a pick-and-mix candy wall. The store decides what goes on the wall. The customer grabs what they like and gets a deal for filling the bag.

Common examples:

• “Pick any 3 candles — save 15%”
• “Build your own 6-pack of socks”
• “Choose 4 supplement flavors for $40”

Mix-and-match vs. fixed bundle — the key difference:

	Fixed Bundle	Mix-and-Match Bundle
Who chooses the items?	The merchant	The customer
Feel	“Buy this set”	“Build your set”
Best for	Starter kits, gift sets	Variety stores, food, apparel, beauty, supplements
Native Shopify support?	✅ Yes (free Bundles app)	❌ No — needs a third-party app

Why Mix-and-Match Bundles Are Worth It

Bundling is one of the most reliable ways to grow revenue without new traffic.

The numbers back it up:

• Research widely cited from McKinsey finds product bundling can lift average order value (AOV) by 20–30%. On a store doing $50,000/month, that’s $10,000–$15,000 in extra monthly revenue — from shoppers you already have.
• Real merchant proof: one Oxify Quantity Breaks user reported a 25% increase in average order value after adding bundles, praising the easy customization (verified review on the app’s Shopify App Store listing).

Why mix-and-match specifically works so well:

• It feels personal. People want what they picked, not a set you forced on them.
• It removes decision fatigue. A clear “choose 3” goal beats scrolling 200 products.
• It moves slow stock. Put quiet products into the mix and they ride along with bestsellers.
• It raises AOV. A small reward for adding “just one more” turns a 1-item order into a 3-item order.

How We Ranked These Apps

We didn’t just count stars. We scored each app on six things real merchants care about:

1. True mix-and-match support — can shoppers genuinely pick items, with min/max rules?
2. Pricing flexibility — fixed price, percentage off, tiered discounts, quantity breaks?
3. Inventory sync — does stock update correctly when a bundle sells? (This breaks more than people expect.)
4. Honest pricing — what does it really cost to run on a live store, not just “install”?
5. Setup speed — can a non-coder launch a bundle in under 15 minutes?
6. Honest review reading — we read what merchants actually wrote, including complaints.

1. Oxify Quantity Breaks — Best Overall Mix-and-Match Bundle App

Rating: 4.9 ★ · Price: From $9.99/month · Free trial: 14 days · Built for Shopify: Yes

👉 View Oxify Quantity Breaks on the Shopify App Store

Oxify Quantity Breaks is our top pick because it gives you a complete bundling toolkit at the lowest paid entry price on this list — $9.99/month.

Here’s the key thing to understand. Most strong bundle apps (Kaching, Fast Bundle, BOGOS) do include mix & match, free gifts, and upsells. The difference is what they cost to actually run:

• Kaching is marketed as “free to install,” but its cheapest real-store plan is $14.99/month — the free plan is for development stores only.
• Fast Bundle’s cheapest live-store plan is $19/month, scaling to $139.
• Easy Bundle Builder starts at $49/month.
• Oxify Quantity Breaks starts at a flat $9.99/month — and mix & match, the bundle builder, quantity breaks, BOGO, free gifts, and analytics are included on every plan, including the cheapest.

For a new or growing store, that’s real money saved every month for the same core toolkit.

What Oxify Quantity Breaks does

• True mix-and-match sets — shoppers pick from a product list or collection, within your min/max rules.
• Gamified Build Your Own Box — a step-by-step layout, fully customizable to your theme.
• Quantity breaks & tiered pricing — “buy more, save more” volume discounts built in.
• Per-product discount control — set a different discount on each product inside one offer (e.g., Product #1 at 10%, Product #2 at a different rule).
• Variant selection in the bundle — shoppers choose the product and its variant (size, strength, scent) in the same step.
• Free gifts and upsells inside the offer — reward a completed bundle or surface an add-on within the same offer.
• BOGO & Buy X Get Y — auto-applied at checkout, no codes for the customer to type.
• Merchandising controls — badge text, badge styles, custom labels, and “selected by default” options.
• A/B testing & built-in analytics — see which bundle actually makes money.
• Schedule campaigns & set exclusions — run seasonal offers and keep certain products out.
• No-code setup — theme-friendly and live in minutes.

A look inside the Oxify offer builder

The Oxify offer builder: set a discount per product, let shoppers pick variants in the bundle, and attach an upsell, free gift, or highlights — all in one offer.

Pricing

Plans are $9.99, $19.99, $39.99, and $69.99/month, scaling by the extra revenue your bundles generate. The important part: the feature set is the same on every tier. You’re paying for revenue headroom, not unlocking core tools. It also carries Shopify’s Built for Shopify badge and holds a 4.9-star merchant rating.

Best for: Stores of any size — from a brand-new shop to Shopify Plus — that want a full bundling toolkit (mix & match, build-a-box, quantity breaks, upsells, free gifts) at the lowest paid entry price.

Honest note: Oxify Quantity Breaks launched in 2025, so its review count is smaller than apps that have been around for years. But its 4.9 rating and Built for Shopify badge show it already clears Shopify’s highest quality bar — and its feature set matches apps that cost far more per month.

2. Kaching Bundles — Best Polished, Proven All-Rounder

Rating: 5.0 ★ (3,500+ reviews) · Price: From $14.99/month ($14.99 / $29.99 / $59.99) · Built for Shopify: Yes

Kaching is a clean, well-built app with one of the biggest review bases on the App Store. It’s a genuinely strong tool — it handles mix-and-match, volume discounts, BOGO, free gifts, product-page upsells, a progress bar, A/B testing, and a revenue dashboard. Merchants consistently praise its fast live-chat support.

Two things to know about pricing. First, despite the “free to install” label, the free plan is for development stores only — the cheapest live-store plan is $14.99/month. Second, paid tiers are capped by extra revenue — Starter covers up to $1,000/month, Scale up to $5,000, Pro up to $10,000 — so a fast-growing store can outgrow a plan and need to upgrade.

Best for: Merchants who want a trusted, feature-rich, well-supported app and don’t mind revenue-capped pricing.

3. Fast Bundle (FBP) — Best for Variety and In-Store Selling

Rating: 5.0 ★ (2,600+ reviews) · Price: From $19/month ($19 / $49 / $139) · Built for Shopify: Yes

Fast Bundle packs in a lot: mix-and-match, fixed bundles, BOGO, Buy X Get Y, product add-ons, an AI-powered “Frequently Bought Together” tool, and an AI bundle image generator.

Its standout is Shopify POS support — it’s one of the few apps here that handles bundle sales in-store as well as online.

The trade-off: the free plan is dev-stores only, paid plans start at $19/month and climb to $139, and the pricing scales with bundle revenue. Model the cost before you commit.

Best for: Stores that sell both online and in person, or want AI-powered bundle features.

4. BOGOS: Free Gift Bundle Upsell — Best for Slot-Based Mix & Match

Rating: 5.0 ★ (3,300+ reviews) · Price: Free plan available, paid from $29.99/month · Built for Shopify: Yes

BOGOS is a heavyweight promotions app used by tens of thousands of merchants. For mix-and-match it offers something most apps don’t: slot-based bundles — slot 1 is T-shirts, slot 2 is trousers, slot 3 is shoes — so customers build across categories. It also covers free gifts, BOGO, Buy X Get Y, volume discounts, and works with POS and Shopify Plus.

The trade-off: BOGOS is broad — if you only need mix-and-match it can feel like a lot of app for the job. Its paid plans are tied to your Shopify plan tier, with per-order fees above set limits.

Best for: Stores that want category-slot mix-and-match alongside a full promotions suite.

5. Bundler — Best Budget Pick

Rating: 4.9 ★ (1,900+ reviews) · Price: Genuine free plan; Premium $6.99/mo, Executive $9.99/mo · Built for Shopify: Yes

Bundler is the value choice — and unlike Kaching or Fast Bundle, its free plan works on live stores, not just dev stores. The free plan covers unlimited basic bundles; mix-and-match and tiered discounts unlock on the $6.99/month Premium plan, and analytics on the $9.99 Executive plan. It also offers bundle landing pages.

The honest limit: Some merchants report Bundler struggles with very high variant counts (one reviewer flagged broken behavior on an 80-variant product). Test it on your catalog first.

Best for: New or small stores that want a genuinely free starting point.

6. BundleSuite — Best for Multi-Step Box Builders

Rating: 4.9 ★ · Price: Free plan available, paid from $19/month · Built for Shopify: Yes

BundleSuite is built around the “build a box” experience. Customers move through clear steps — pick a base, add extras, choose a gift — with templates that keep the flow tidy. It also handles fixed bundles, infinite-option bundles, quantity breaks, and BOGO.

Best for: Stores where the guided box-building journey matters as much as the products — snacks, skincare, gift sets.

7. Easy Bundle Builder — Best for Gifting-Focused Stores

Rating: 4.9 ★ · Price: Free up to $500/month in bundle sales, then from $49/month · Built for Shopify: Yes

Easy Bundle Builder focuses on “build your own” bundles with genuinely strong gifting features — greeting cards, gift boxes, and multi-step guided flows. It also offers deep discount rules and subscription/3PL integrations.

It’s powerful — and priced like it. Paid plans start at $49/month, the highest entry point here, and scale with bundle revenue.

Best for: Established brands selling giftable products that can absorb the higher cost.

8. Simple Bundles & Kits — Best for Inventory and 3PL

Rating: 4.9 ★ · Price: Free plan covers up to 3 bundles, then paid plans · Built for Shopify: Yes

Simple Bundles shines on the back end. It breaks every bundle into individual SKUs so stock stays accurate, and connects with POS, ERP, WMS, and 3PL systems for clean fulfillment. It supports mix-and-match, subscription bundles, B2B multipacks, AI-suggested bundles, and can bypass Shopify’s 2,048-variant limit.

Best for: Stores that ship physical kits and need rock-solid inventory and warehouse sync.

9. Dealeasy — Best for Mix & Match Plus a Discount Toolkit

Rating: 4.9 ★ · Price: Free up to 50 orders/month, then from $8.99/month · Built for Shopify: Yes

Dealeasy is primarily a volume-discount app, but it includes solid mix-and-match with two pricing models — fixed price (“3 products for $25”) and dynamic pricing (each product adds its own price). You also get volume discounts, BOGO, cart goals, and free gifts in one install.

The trade-off: its bundle UI is less polished than dedicated builders, and pricing is based on your store’s total order count, not just bundle orders.

Best for: Stores that want mix-and-match alongside a broad discount toolkit in one app.

10. Bundly — Best Design-First Option

Rating: 5.0 ★ · Price: From $29/month · Built for Shopify: No

Bundly is the best-looking app here. Merchants repeatedly say it feels native and premium out of the box, where other bundle apps look clunky. You build the bundle, then style it — all inside the app.

Two limits to know: Bundly is the only app on this list without the Built for Shopify badge, so you lose Shopify’s performance guarantees. It’s also not compatible with POS or subscription apps.

Best for: DTC brands selling curated gift boxes that prize a beautiful storefront and don’t need POS or subscriptions.

Feature & Pricing Comparison

Most mature bundle apps cover the core features. The real difference is what you actually pay to run them on a live store. Here’s an honest side-by-side.

	Oxify Quantity Breaks	Kaching	Fast Bundle	BOGOS	Bundler
Mix-and-match bundles	✅	✅	✅	✅	✅
Build-a-box	✅	✅	✅	✅	❌
Quantity breaks	✅	✅	✅	✅	✅

Cheapest paid plan (live store)	$9.99	$14.99	$19	$29.99	$6.99
Free plan on a live store?	Trial only	❌ Dev only	❌ Dev only	✅	✅

Table reflects live App Store listings, May 2026.

The honest takeaway: Oxify Quantity Breaks matches the feature set of the big, established apps — at the lowest paid entry price among full-featured options ($9.99/month). Bundler is cheaper at the very bottom and has a real free plan, but it lacks build-a-box, in-offer free gifts, and upsells. For a complete toolkit at the best price, Oxify is the pick.

How to Set Up a Mix-and-Match Bundle on Shopify (5 Steps)

Most app-comparison articles skip this — but setup is half the battle. Here’s the general flow, which works with Oxify Quantity Breaks and most apps on this list:

1. Install the app and create a new offer. No code needed.
2. Choose your products or collection. Pick which items shoppers can mix from — a hand-picked list or a whole collection. Set a discount per product if your app supports it.
3. Set your rules. Decide minimum and maximum items (e.g., “choose 3 to 6”) and your discount type — fixed price, percentage off, or tiered.
4. Add extras and style it. Attach an upsell or free gift, add a badge, and match colors and fonts to your theme.
5. Test on mobile, then publish. Build one real bundle, check it on a phone, and place a test order before going live.

Most merchants get a first bundle live in under 15 minutes.

6 Tips to Make Your Mix-and-Match Bundle Convert

A great app is only half the job. Here’s how to make the bundle sell:

1. Use the “rule of three.” Offer three discount tiers — like 10%, 15%, and 20% off. More than three confuses people.
2. Show how close they are to the next reward. “Add 1 more to unlock 15% off” pulls shoppers forward. Behavioral experts call this the goal-gradient effect — people speed up as they near a goal.
3. Add a free gift at the top tier. A free gift for completing the bundle is a powerful nudge — and with apps like Oxify you can build it right into the offer.
4. Limit choices per step. Group items into clear categories with 3–5 options each. Too many choices freeze the shopper.
5. Design mobile-first. Most shoppers are on a phone. A clumsy mobile builder loses the sale.
6. Watch your page speed. Check Shopify’s PageSpeed before and after installing. Apps using Shopify theme app blocks (the Built for Shopify standard) load efficiently.

How to Choose the Right App for Your Store

Three quick rules before you commit:

1. Always use the free trial. Build one real bundle and test it on mobile.
2. Read the pricing model, not just the headline. “Free to install” often means the free plan is dev-stores only — check the real cost for a live store, and whether tiers are revenue-capped.
3. Match the app to your stage. A new store doesn’t need a $49/month enterprise plan; a 3PL-heavy store can’t skip inventory sync.

For most Shopify merchants — new or scaling — Oxify Quantity Breaks hits the best balance: the full bundling toolkit on every plan, the Built for Shopify badge, and a $9.99 paid entry price.

Frequently Asked Questions

The Bottom Line

Mix-and-match bundles turn browsers into bigger buyers. They make shopping feel personal, cut decision fatigue, and lift average order value — all without discount codes or a cluttered store. And since Shopify’s native Bundles app can’t do mix-and-match, the right third-party app is essential.

Most mature apps cover the core features. The deciding factor is value: getting the full toolkit at a price that makes sense. That’s why Oxify Quantity Breaks is our 2026 pick — mix-and-match, build-a-box, quantity breaks, upsells, and free gifts, all on a flat $9.99/month plan (the lowest paid entry price among full-featured apps), with the Built for Shopify badge.
