Product Bundles Guide
Boost Average Order Value (AOV) by offering curated product bundles and volume discount packages directly to shoppers.
What is a Product Bundle Offer?
A Bundle Offer groups two or more complementary items together (e.g. Camera + Tripod + SD Card or Buy a 3-Pack & Save 20%) and presents them to shoppers with a bundled discount incentive.

Complete-the-Set & Volume Strategies
- Complete-the-Set: Automatically recommended when a shopper adds one constituent item to their cart. Cartwheel computes the combined original price and displays missing items at a bundle discount.
- Frequently Bought Together: Pair a main product with matching accessories (e.g. Laptop + Protective Sleeve + Wireless Mouse).
- Volume Discount Multi-Packs: Offer tier discounts for purchasing multiple quantities of the same item (e.g. 1 Unit (Full Price), 2 Units (15% OFF), 3 Units (25% OFF)).
