What is a Product Bundle?

A Product Bundle is a merchandising strategy where two or more individual products are combined and offered as a single purchasing unit (e.g. “Shaving Starter Kit” containing a Razor, Replacement Blades, and Shaving Cream).

Bundle Types

  1. Fixed Bundle: Pre-defined set of items sold together under one title.
  2. Multipack: Multiple units of the identical variant sold at a volume discount (e.g. 3-Pack of White T-Shirts).
  3. Mix & Match (Custom Bundle): Shopper selects items from multiple option categories to build a custom kit.

Developer Takeaway

Inventory Breakdown Logic: When a bundle is purchased, inventory must be decremented from each individual component variant record in the warehouse. Never maintain a separate disconnected inventory count for a virtual bundle entity.
