Product bundling is selling two or more products together at a discounted price. It's one of the most effective methods to increase average order value, clear inventory, and boost customer lifetime value. Sellers using bundle strategies on Amazon and major marketplaces achieve 20-35% higher cart values than competitors.
1. What Is Product Bundling?
- Definition: Selling two or more products packaged together under a single SKU
- Purpose: Deliver value to customers, generate higher revenue for sellers
- Difference: "Cross-sell" is a suggestion; "bundle" is sold as a ready package
- Other names: Kit, set, combo, multi-pack, value pack
