Shopify Product Bundles: The Complete Guide (2026)
Product bundles help Shopify brands raise average order value by selling products that work well together. This guide covers the main bundle types, how to set them up and price them, where to show them, and how to measure results.
What Are Product Bundles?
A product bundle is a group of products sold together as one offer, usually at a single combined price. On Shopify, bundles can be fixed sets you create in advance, mix-and-match offers where shoppers choose their own items, or dynamic bundles that change based on what each shopper is browsing.
Bundles help shoppers find products that work well together, and they help brands raise average order value (AOV) without relying on deeper sitewide discounts. For a quick definition, see what bundles mean in ecommerce.
Why Bundles Matter
Here's what bundles have done for a few Rebuy brands:
- 63.78% AOV lift for jewelry brand Olive & Piper after rebuilding its Bridal Bundle promotion with Rebuy Bundle Builder
- 16% higher conversion rate with Bundle Builder for York St Brands, the company behind Boost Lab, The Breakout Hack, and Bouf
- 21.5% AOV lift for paper flower brand Unwilted in November 2025, after letting shoppers build their own bouquets
"The Bundle Builder makes it an easy, fluid, seamless experience."
Benefits and Risks of Bundling
A higher AOV is the headline, but bundles do a few other jobs well. They can:
- Move slow stock by pairing it with a bestseller.
- Launch new products next to ones shoppers already trust.
- Help shoppers discover more of your catalog, which gives them more reasons to come back.
- Lower fulfillment cost per item, since one box ships several products.
They come with risks, too. Discount too deeply and you trade margin for volume. Sell some items only inside a bundle and shoppers who wanted one thing may leave with nothing. And a discount code stacked on an already-discounted bundle can push the order below cost. Common Bundling Mistakes, further down, covers how to avoid each one.

Types of Product Bundles
Most Shopify bundles fall into one of five types. The right one depends on your catalog, your margins, and how much choice you want to give shoppers.
| Bundle type | How it works | Best for |
|---|---|---|
| Fixed | A preset group of products sold together at one price | Gift sets, starter kits, routines |
| Mix-and-match | Shoppers choose any items from a set collection | Catalogs with many interchangeable products |
| Build-your-own | Shoppers build a bundle step by step, often with tiered pricing | Sample packs, boxes, customizable kits |
| Volume or tiered | The discount grows as shoppers buy more units or items | Consumables and replenishment products |
| Dynamic | Bundle contents adapt to each shopper based on behavior and product data | Large catalogs and returning customers |
Fixed Bundles
Fixed bundles are the simplest to launch. You choose the products, set the price, and sell the set as one item. They work best when the products are clearly meant to be used together, like a three-step skincare routine.
Mix-and-Match and Build-Your-Own Bundles
These bundles give shoppers control. Instead of buying a preset kit, they pick the items they want, and the price adjusts as they go. Learn how to set one up in How to create build-your-own bundles on Shopify, or see how Rebuy Bundle Builder handles it.
Volume and Tiered Bundles
Volume bundles reward shoppers for buying more, such as 10% off two items and 15% off three. They are a good fit for products people use up and reorder.
Dynamic Bundles
Dynamic bundles change based on who is shopping. Instead of one bundle for everyone, each shopper sees products that match what they are viewing or have bought before. See how Rebuy Dynamic Bundles work.
How to Create Bundles on Shopify
You have two main ways to sell bundles on Shopify: Shopify's own Bundles app or a third-party bundle app. Both can work. The choice comes down to how much flexibility you need.
Shopify's Native Bundles App
Shopify offers a free Bundles app for creating fixed bundles and multipacks. It is a good starting point for simple offers, but it has fewer options for shopper-built bundles, personalization, and placement outside the product page.
Third-Party Bundle Apps
Bundle apps add options the native app does not cover, such as mix-and-match and build-your-own bundles, tiered pricing, personalized bundle recommendations, and placements in the cart, checkout, and post-purchase. Many also include A/B testing and reporting.
Shopify Bundles vs. Rebuy
Shopify Bundles is a solid free starting point if you need a few simple fixed bundles. Once you want shoppers to build their own, tiered discounts, or personalized picks, a dedicated bundle app does more. Here's how Shopify's app compares with Rebuy's bundle tools. (Yes, Rebuy is ours, so we've stuck to what each one does.)
| Shopify Bundles | Rebuy (Bundle Builder and Dynamic Bundles) | |
|---|---|---|
| Price | Free on all Shopify plans | Part of the Cart & Merchandising package, with a 14-day free trial |
| Bundle types | Fixed bundles and multipacks | Build-your-own bundles (Bundle Builder) and "frequently bought together" bundles on product pages (Dynamic Bundles) |
| Build-your-own | No | Yes, a guided, step-by-step flow with min and max rules for each step |
| Personalized products | No | Yes, AI or your own rules choose which products appear |
| Discounts | A set price for each bundle | Tiered discounts by quantity or subtotal, as a percentage or fixed amount |
| Gift with purchase | No | Yes, built into Bundle Builder |
| Subscriptions | Can’t be sold with subscriptions or other selling plans | Bundle Builder can offer a subscription option when you use a subscription app built on Shopify selling plans |
| Inventory | Syncs stock for each item in the bundle (total stock, not by location) | Uses your existing products, so there are no new bundle SKUs to manage |
| A/B testing | No | Yes |
| Best for | A few simple fixed bundles or multipacks | Build-your-own boxes, tiered offers, gifting, and personalized bundles |

Setting Up Your First Bundle
- Start with your order data. Look for products customers already buy together.
- Choose a bundle type. Match it to your catalog and goals.
- Set your price. Offer clear savings while protecting margin.
- Pick a placement. Product pages are a common first step.
- Check inventory sync. Make sure each item in the bundle updates stock correctly.
- Launch and measure. Track AOV and attach rate from day one.
Inventory and Fulfillment
How you build a bundle decides how its stock works. The safest setup reduces inventory for each individual item in the bundle, so you never sell a bundle you can't ship.
- Shopify Bundles app: Stock syncs in real time with the items inside each bundle. Two things to know: it tracks total stock rather than stock by location, and the bundle price doesn't change when an item's price does, so update it by hand.
- A bundle listed as its own product: Quick to set up, but its stock lives apart from the items inside it. You adjust counts yourself, which makes overselling easy.
- A third-party bundle app: Most reduce stock for each item when a bundle sells. Confirm this, and test it with a real order, before you launch.
Plan for sell-outs, too. If one item runs out, the whole bundle usually goes with it. Pick a backup product in advance, or pause the bundle until you restock. And check how bundles appear on packing slips so your fulfillment team knows what to pick.

How to Price a Bundle
A good bundle price gives shoppers a clear reason to buy the set while keeping your margin healthy. Start with a simple formula, then test.
A Simple Pricing Formula
Bundle price = combined retail price of the items − your bundle discount
Bundle margin = (bundle price − combined cost of goods) ÷ bundle price
Example
| Item | Retail price | Cost of goods |
|---|---|---|
| Cleanser | $24.00 | $6.00 |
| Serum | $38.00 | $9.00 |
| Moisturizer | $32.00 | $8.00 |
| Total | $94.00 | $23.00 |
At a 15% bundle discount, the bundle sells for $79.90. The margin is ($79.90 − $23.00) ÷ $79.90, or about 71%.
Pricing Tips
- Show savings in dollars for higher-priced bundles and as a percentage for lower-priced ones.
- Avoid deep discounts on best sellers that already sell well on their own.
- Test two or three discount levels before settling on one.
Where to Show Bundles
Where you show a bundle matters as much as what's in it. Each placement fits a different moment in the shopping journey.
| Placement | Bundle type that fits | Why it works |
|---|---|---|
| Product page | Fixed or dynamic | The shopper is already considering a related item |
| Cart | Add-ons and tiered offers | The shopper has decided to buy, so small additions feel easy |
| Checkout | Low-cost complementary items | A last, simple offer before payment |
| Post-purchase | Replenishment or complementary items | The shopper can add to their order without re-entering payment details |
| Landing page | Build-your-own | Gives shoppers room to explore options and build their own set |
Most brands start on the product page, then expand to the cart and post-purchase once they see what converts.
How to Promote Your Bundles
Placement gets a bundle in front of shoppers who are already browsing. Promotion brings in the rest. A few places worth adding:
- Homepage and collections: Feature your best bundle on the homepage, or create a Bundles collection so shoppers can compare them in one place.
- Email and SMS: Add a bundle to post-purchase and replenishment messages, when shoppers already know and like the product.
- Gift guides: Bundles make easy gifts. Group them by price, like "Gifts under $50," in holiday guides and BFCM campaigns.
- Visible savings: Show the combined price of the items next to the bundle price so the deal is clear at a glance.
- A name that sells: Call it what it does for the shopper. "Morning Routine Kit" explains itself. "Bundle 3" does not.
How Bundles Increase AOV and How to Measure Results
Bundles raise average order value by adding items to an order that a shopper might not have found on their own. They also make the decision easier: one offer instead of several separate choices.
For a deeper look, read How bundles increase AOV.
Metrics to Track
- Average order value (AOV) — Compare orders with and without a bundle.
- Bundle attach rate — The share of orders that include a bundle.
- Bundle conversion rate — How often a bundle view leads to a purchase.
- Margin per order — Confirms that discounts aren't eating into profit.
- Bundle revenue — Total revenue from bundled orders, broken out by placement.
Testing Your Bundles
- Test one change at a time, such as price, products, or placement.
- Run each test for at least two full business cycles.
- Compare results against a control group that doesn't see the bundle.
Bundle Strategies by Brand Type
The best bundle strategy depends on what you sell and how often customers come back. Here's how bundles typically work across a few common brand types.
Subscription Brands
Starter kits make a strong first order, and add-on bundles give subscribers a reason to increase each shipment.
One catch: bundles built with Shopify's native bundle tools can't be sold with selling plans, and subscriptions are a selling plan. If you want subscribe-and-save bundles, choose a bundle app that works with your subscription app, such as Recharge, Skio, or Stay.ai. Read more in Bundles for subscription brands.
Beauty and Skincare
Routine bundles, like cleanser, serum, and moisturizer, help shoppers buy a complete regimen instead of guessing which products work together.
Food and Beverage
Variety packs and sample bundles lower the risk of trying something new, and build-your-own boxes let shoppers pick favorites.
Apparel and Accessories
Complete-the-look bundles pair a core item with matching pieces, which works well on product pages and in the cart.
Bundles for BFCM and the Holidays
Black Friday and Cyber Monday are the biggest bundle weeks of the year. Shoppers are buying gifts, comparing deals, and stocking up, so bundles do extra work:
- Gift sets answer "what should I get them?" in one click.
- Tiered offers, like "buy 2, save 10%; buy 3, save 15%," lift order value without a sitewide discount.
- Slow stock moves faster when you pair it with a bestseller before the new year.

- York St Brands (beauty): Replaced manual bundle and free-gift setups across three brands with mix-and-match bundles and tiered savings. Conversion rose 16% with Bundle Builder.
Common Bundling Mistakes
Most bundle problems come from a few avoidable mistakes.
1. Bundling Products That Don't Belong Together
A bundle should solve a clear need. If shoppers can't tell why the items are grouped, they won't buy the set. Use order data to find products customers already buy together.
2. Discounting Too Deeply
A bigger discount doesn't always mean more sales. Check your margin on every bundle, and test smaller discounts first.
3. Ignoring Inventory
If one item in a bundle sells out, the whole bundle can become unavailable or oversold. Make sure your app tracks stock for each item.
4. Showing Bundles in Only One Place
A bundle that only appears on one product page reaches a small share of shoppers. Test the cart, checkout, and post-purchase too.
5. Setting It and Forgetting It
Catalogs, seasons, and customer behavior change. Review bundle performance regularly and refresh underperforming offers.
Frequently Asked Questions
What is a product bundle on Shopify?
A product bundle is a group of products sold together as one offer, usually at a combined price. Shopify merchants use bundles to raise average order value and help shoppers buy products that work well together.
Does Shopify have a built-in bundles feature?
Yes. Shopify offers a free Bundles app for fixed bundles and multipacks. Merchants who want mix-and-match, build-your-own, or personalized bundles typically use a third-party app.
What's the difference between a fixed bundle and a dynamic bundle?
A fixed bundle contains the same products for every shopper. A dynamic bundle changes based on each shopper's behavior and the product they're viewing.
How much should I discount a bundle?
Many brands start with a modest discount and test from there. The right amount depends on your margins, so calculate bundle margin before choosing a discount.
Do bundles increase average order value?
Bundles add items to an order that shoppers might not have chosen on their own, which raises the order total. Track AOV with and without bundles to measure the impact on your store.
How do bundles affect inventory?
The safest setup reduces stock for each individual item in a bundle. Confirm that your bundle app does this so you don't oversell.
What is a build-your-own bundle?
A build-your-own bundle lets shoppers choose the items in their bundle, often with a price that adjusts as they add products. It works well for sample packs, boxes, and kits.
Where should I show bundles on my store?
Product pages are the most common starting point. Many brands also show bundles in the cart, at checkout, and after purchase.
