Why the share is low: code checks are run against real carts, including plenty this code was never eligible for. Most codes only apply to certain products or need a minimum cart, so a working code still fails on every cart it never fit.

Shoppers who tried it at checkout entered this code in their cart in the last 14 days, each checkout counted once. Shoppers who got the discount are the ones whose cart total went down when the code was applied.

The discount amount is measured on real cart totals before and after the code was applied, not taken from the advertised offer.

Code confidence is our agents' read on how likely this code is to work. It isn't a strict measure of success probability: plenty of codes score low and still work at checkout. It was last recalculated today.
