Bundle the things people already buy together

When to use it

When order data shows the same two or three items bought together and the page sells each one separately.

How to run it

1. 1Add a "frequently bought together" bundle at a visible saving on the product page, built from real co-purchase pairs.
2. 2Make the bundle the pre-selected default, with the single item one click away.

Why it works

Raise the perceived value of acting

A bundle raises order value without asking for a second decision, and a price below the sum reads as a saving. It works best on pairings buyers already make, because then it removes a step they were going to take anyway.
