A bundle combines products at a combined price that's lower than buying each item individually. The discount doesn't need to be large to be effective - 10-15% off is typically enough to make the bundle feel like a better deal while maintaining workable margin. The key is that the bundled products are things the customer genuinely wants together, not filler items padded around a hero product.
Bundle types that work
Starter/kit bundles. Everything a new customer needs to get started with your product. A coffee brand selling a "Home Barista Starter Kit" (bag of beans + grinder + filters + milk frother) gives a first-time buyer everything in one purchase. This works because: the customer was going to buy these items eventually, they save by buying together, and the brand makes a larger first transaction that improves LTV from the start.
Quantity bundles. "Buy 2, save 10%" or "Buy 3, get 1 free." Works best for consumable products with predictable replenishment. The customer trades a larger upfront spend for a lower per-unit cost. A supplement brand doing this captures several months of purchases in a single transaction, reducing future acquisition cost.
Complementary product bundles. Products that are naturally used together but sold separately by default. A skincare brand selling a "Complete AM Routine" (cleanser + vitamin C serum + SPF) gives customers a curated system rather than asking them to assemble it themselves. This works because it reduces decision fatigue and provides curation value beyond the discount.
Build-your-own bundles. The customer selects their own combination from a defined set of products at a bundle price. Works well for flavour-variety products (pick 4 protein flavours), gift sets (choose any 3 candles), or customisable kits. Higher perceived value because the customer is in control.
Implementing bundles on Shopify
Native Shopify approach (simple bundles). Create a new product in Shopify representing the bundle. Price it at the bundle price. The product description explains what's included. This is the simplest approach but has a significant limitation: inventory isn't linked between the bundle product and the individual component products. If you sell out of individual components, the bundle shows as available until you manually update it.
Shopify Bundles app (free, from Shopify). Shopify's own bundle app, available free in the App Store. Creates bundles that are linked to component product inventory - when a component sells out, the bundle reflects it automatically. Supports fixed bundles and multipack bundles. Good for straightforward bundle needs without paying for a third-party app.
Bundle Builder or Fast Bundle apps. Third-party bundle apps (from $19-$49/month) support build-your-own bundles, tiered discounts, mix-and-match selections, and more complex bundle logic. Worth the monthly fee if you want customer-configurable bundles or need more flexibility than the native Shopify Bundles app provides.
Pricing strategy
The bundle discount needs to be meaningful enough to motivate the purchase but not so large that it erodes margin significantly. The range that works for most products:
- 10% off for complementary product bundles
- 15% off for quantity bundles (buy more of the same)
- 20% off for starter kit bundles (higher perceived complexity, higher discount expectation)
Show both the original combined price and the bundle price on the product page. "Worth £89 separately - get the bundle for £76" makes the saving concrete and motivates the purchase more than just showing the bundle price alone.
Where to surface bundles
Bundles that live only on their own product page convert at a fraction of their potential. Surface them:
- On individual component product pages: "Frequently bought together" or "Complete the set" showing the bundle below the add-to-cart button
- In the cart: "Upgrade to the bundle and save £X" when a component product is in the cart
- On collection pages: A featured bundle card in the collection grid
- In email marketing: Post-purchase emails recommending the bundle to customers who bought a single component
What to avoid
Bundles with obviously low-value filler products. A bundle that adds a low-quality item to justify a higher price point damages the perceived quality of the hero products. Every item in a bundle should be something the customer would independently consider worth having.
Discount so large it trains customers to wait for bundles. If your bundle discount is 40%, customers learn not to buy individual products because the bundle is always a better deal. A 40% bundle discount also makes it very hard to sustain margin over time.
Bundles on products with no natural relationship. Shopify's "frequently bought together" algorithm surfaces products that are statistically often purchased in the same session. If you're creating bundles, use this data to identify which products customers actually pair - not which products you want to sell more of.
