10 Best Shopify Mix and Match Bundle Apps (October 2026): Prices & Free Plans Verified

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 compared the top options on what actually matters — pricing rules, inventory sync, storefront design, and setup speed — and re-checked every rating, price, free plan and Built for Shopify badge against the live App Store listings on October 11, 2026, then re-read all ten listings on October 13, 2026 (review counts updated; Simple Bundles & Kits moved from 4.9 to 4.8 stars).

Disclosure: Oxify publishes this guide and makes Oxify Quantity Breaks & BYOB (ranked first below) and Oxify Cart Drawer & Upsells. Our app is young (launched July 30, 2025) with 13 reviews, against 6,000+ on Kaching, so each app, ours included, has a "skip it if" or limit line.

Top 10 Mix-and-Match Bundle Apps — Quick Comparison

Ratings, review counts and pricing are from each app's live Shopify App Store listing, re-checked October 11, 2026 and re-read October 13, 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.

What the free-plan check found (October 11, 2026): a free plan is not always a free mix-and-match plan. Bundler's free plan does not list mix and match; that starts on its $9.99/month Premium plan. BOGOS lists mix and match on its free plan but stops at 30 lifetime orders. Easy Bundles lists mix and match on its free plan up to $500/month of bundle sales, but says the free plan does not apply to Shopify Plus and Advanced plans. Simple Bundles' free plan covers 3 bundles and 50 orders a month, build-your-own included. Kaching, Fast Bundle and BundleSuite are free only on development stores.

In a hurry? Pick by your situation:

• Want every feature on one flat plan, no caps → Oxify Quantity Breaks & BYOB (our app)
• Want a free plan that includes mix and match → Easy Bundles or Simple Bundles (BOGOS stops at 30 lifetime orders; Bundler's mix and match starts at $9.99/month)
• Sell in-store and online → check the POS line in each listing: Fast Bundle, Kaching, BOGOS, Bundler, BundleSuite, Easy Bundles and Simple Bundles name Shopify POS; Bundly says it is not compatible
• Ship complex kits, need inventory sync → Simple Bundles & Kits
• Design is your #1 priority → Bundly

Best Mix-and-Match Bundle App for Startups and New Shopify Stores

For a new store, the best mix-and-match bundle app is one whose free plan already includes mix and match: Easy Bundles (up to $500 a month of bundle sales) or Simple Bundles & Kits (3 bundles and 50 orders a month). Here is the pick by stage, from the live listings read October 13, 2026.

What we would do on a new store: launch one "pick any 3, save 15%" set from a single collection on a free plan (Easy Bundles, or Simple Bundles if a warehouse picks your orders), test it on a real phone, and compare AOV on bundle orders with your usual AOV for two to four weeks before paying. Oxify Quantity Breaks & BYOB has no free plan for live stores, only a 14-day trial, so it is not the cheapest start; it earns its $14.99 when you also want quantity breaks, BOGO and free gifts without a second app. We publish this guide and make Oxify, so check every price on the listing before you install.

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:

Why Mix-and-Match Bundles Are Worth It

Mix-and-match bundles go after one number: how much each visitor spends, without paying for more traffic.

What the evidence shows:

• One merchant review on the Oxify Quantity Breaks & BYOB listing reports a "25% increase in the average order value" and praises the "Easy customisation option" (Go Ayurveda Dhanvantri · India · Shopify App Store review, 30 September 2025). It is a self-reported figure from one store, not a controlled test.
• Be wary of any generic "bundling lifts average order value (AOV) by X%" figure: it depends on the store, the offer and the baseline. The reliable test is your own: compare AOV on bundle orders with your usual AOV for two to four weeks. Kaching, Fast Bundle and Oxify Quantity Breaks all list A/B testing (see the comparison table below).

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 & BYOB (Our App): Best All-in-One Flat-Price Bundle App (Quantity Breaks, BOGO, Free Gifts, BYOB)

Rating: 4.9 ★ (13 reviews) · Price: $14.99/month or $129.99/year (one plan, every feature) · Free trial: 14 days · Built for Shopify: Yes

👉 View Oxify Quantity Breaks on the Shopify App Store

Oxify Quantity Breaks is our app, and we rank it first because it gives you a complete bundling toolkit on one flat plan — $14.99/month, or $129.99/year.

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 Bundles is free up to $500/month of bundle sales, then from $29/month.
• Oxify Quantity Breaks is a single flat $14.99/month plan ($129.99/year, save 28%) — and mix & match, the bundle builder, quantity breaks, BOGO, free gifts, and analytics are all included, with a 14-day free trial.

For a new or growing store, that means one predictable price for the full toolkit, with no revenue tiers to outgrow.

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

There is one paid plan, $14.99/month or $129.99/year (save 28%), with a 14-day free trial. The important part: every feature is included. There are no revenue tiers and no bundle or order caps, so you never pay more to unlock core tools. It also carries Shopify's Built for Shopify badge and holds a 4.9-star merchant rating.

Best for: Stores past the free-plan stage that want a full bundling toolkit (mix & match, build-a-box, quantity breaks, upsells, free gifts) on one flat plan with no bundle or order caps.

Skip it if: you want a permanent free plan on a live store (Easy Bundles and Simple Bundles have one that includes mix and match), you want the longest review history (13 reviews against Kaching's 6,282), or you sell bundles in a physical shop — the Oxify listing doesn't name Shopify POS, and seven of the other nine listings do.

Honest note: Oxify Quantity Breaks launched on July 30, 2025 (per its App Store listing), so its review count is smaller than apps that have been around for years. Its 4.9 rating comes from 13 reviews, so weigh it accordingly. The Built for Shopify badge means Shopify checked it against its performance, design and integration requirements.

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

Rating: 5.0 ★ (6,282 reviews) · Price: From $14.99/month ($14.99 / $29.99 / $59.99 on the listing, up to $299 on Kaching's site) · Built for Shopify: Yes · View on the App Store

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, and Kaching's own pricing page continues to $99, $149, $199 and $299/month above that — 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 ★ (3,543 reviews) · Price: From $19/month ($19 up to $1,000 of bundle sales / $49 up to $3,000 / $139) · Built for Shopify: No (badge not shown, October 13, 2026) · View on the App Store

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 listing highlights Shopify POS support: you can create bundle offers for the POS with "POS-ready" options. That is no longer rare on this list — the Kaching, BOGOS, Bundler, BundleSuite, Easy Bundles and Simple Bundles listings also name POS, while Bundly's says it is not compatible.

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 ★ (4,485 reviews) · Price: Free plan (30 lifetime orders), paid from $29.99/month (Shopify Basic stores) · Built for Shopify: Yes · View on the App Store

BOGOS is a heavyweight promotions app; its listing says it is used by 82,900+ Shopify stores. 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: $29.99/month on Shopify Basic, $49.99 on Grow, $69.99 on Advanced and $109.99 on Plus, each with a monthly order allowance (300, 600, 1,000 and 2,000) and $0.05 per extra order. The free plan lists mix and match but stops at 30 lifetime orders, so treat it as a trial; the build-a-box builder is listed from the paid Basic plan.

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

5. Bundler — Best Budget Pick

Rating: 4.9 ★ (2,729 reviews) · Price: Free plan (no mix and match); Premium $9.99/mo adds mix and match; Executive $19.99/mo adds analytics · Built for Shopify: Yes · View on the App Store

Bundler is the value choice — and unlike Kaching or Fast Bundle, its free plan works on live stores, not just dev stores. But read the tiers: on the October 11, 2026 listing the free plan covers buy X get Y, volume discounts and quantity breaks, product-page upsells and Shopify POS, while Mix & Match (plus tiered and sectioned mix and match), custom landing pages and funnel upsells are listed on the $9.99/month Premium plan and bundle analytics on the $19.99 Executive plan. Those paid plans were $6.99 and $9.99 in May 2026.

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 the cheapest paid route to mix and match ($9.99/month).

6. BundleSuite — Best for Multi-Step Box Builders

Rating: 5.0 ★ (549 reviews) · Price: Free for development stores only; paid from $12/month (up to $1,000 of bundle sales), then $29 (up to $5,000) · 7-day trial · Built for Shopify: Yes · View on the App Store

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 ★ (1,415 reviews) · Price: Free up to $500/month in bundle sales, then $29/month (up to $3,000), $49/month (up to $5,000) and $99/month (up to $10,000) · 15-day trial · Built for Shopify: Yes · View on the App Store

Easy Bundle Builder focuses on "build your own" bundles, with gift boxes among its listed bundle types and single or multi-step guided flows. It also offers deep discount rules, subscription bundles and 3PL inventory sync.

Check which tier unlocks what. The free plan lists mix and match, fixed and volume bundles; the single and multi-step bundle builder and landing-page templates start at Essential ($29/month); custom personalization fields, bundle add-ons, free gifts and subscription bundles start at Growth ($49/month). The listing says the free and Essential plans do not apply to Shopify Plus and Advanced plans. (The listing now names it "Easy Bundles: Bundle Builder".)

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

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

Rating: 4.8 ★ (803 reviews) · Price: Free plan covers 3 bundles and 50 monthly orders, then $14, $39 or $149/month · Built for Shopify: Yes · View on the App Store

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 ★ (636 reviews) · Price: Free up to 50 orders/month, then $9/month (up to 500) and $19/month · 30-day trial · Built for Shopify: Yes · View on the App Store

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: 4.9 ★ (64 reviews) · Price: $29/month (unlimited orders and bundle sales) or $59/month · 14-day trial · Built for Shopify: Yes · View on the App Store

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.

The limit to know: Bundly has the smallest review base here (64 reviews), so there is less production evidence behind it. Correction: an earlier version of this article said Bundly lacked the Built for Shopify badge; its listing shows the badge as of October 13, 2026. The app on this list without the badge today is Fast Bundle.

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.

Pricing, badge and POS rows re-checked against live App Store listings on October 11, 2026 (prices and badges re-read October 13, 2026); feature rows are from each app's listing and documentation, and "partial" means the listing covers it only on some plans or in part.

The honest takeaway: Oxify Quantity Breaks covers the core features in this table on one flat plan ($14.99/month, the same starting price as Kaching). Bundler is cheaper at the very bottom — mix and match from $9.99/month — but its free plan doesn't include it, and its listing covers build-a-box, in-offer free gifts and upsells only in part. Oxify's listing doesn't name Shopify POS, which most of the others do. For a complete toolkit with no tiers or caps, Oxify is the pick; if you sell in a physical shop, check POS first.

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.

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; our guide on how many tiers a quantity break should have covers spacing.
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. Price the bundle against your free-shipping line. Shoppers see both in the same cart, so check where your own line sits before you set the "pick 3" price.
6. Watch your page speed. Run PageSpeed Insights on a product page before and after installing. Shopify's own rule is that an app must not lower your storefront's Lighthouse performance score by more than 10 points (Shopify's app performance rules, checked October 11, 2026), and Built for Shopify repeats the same limit.

Mix-and-Match Gift Sets on Shopify: Which App Fits?

Gift sets are the most common mix-and-match use case we see — "pick any 3 candles", "build a skincare box", "choose 6 snacks". They need three things beyond a basic bundle: a fixed or tiered price for the set, variant choice for each item, and a gift step (box, card or free gift) at the end.

• Simple "pick any X" gift sets on the product page → Oxify Quantity Breaks & BYOB (our app) or Kaching Bundles.
• Multi-step gift boxes → Easy Bundles (multi-step builder from its $29/month plan) or BundleSuite (multi-step bundles from $12/month).
• Design-led gift boxes for a premium brand → Bundly.
• Physical kits that must stay accurate in a warehouse or 3PL → Simple Bundles & Kits.
• A free gift inside the set → BOGOS or Oxify; see how to add a free gift with purchase on Shopify.

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.

Starting out? Use a free plan that includes mix and match (Easy Bundles or Simple Bundles). Want the most reviews? Kaching. Want the full bundling toolkit on one flat plan, with the Built for Shopify badge and a 14-day free trial? Oxify Quantity Breaks & BYOB, our own app.

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 on a plan that stays predictable. If that is what you want, Oxify Quantity Breaks & BYOB (our app) is our pick: mix-and-match, build-a-box, quantity breaks, upsells, and free gifts, all on one flat $14.99/month plan with a 14-day free trial, plus the Built for Shopify badge. If you want to start free, use Easy Bundles or Simple Bundles; if you want the most reviews, Kaching.
