A "40% off" sign means nothing on its own. See instantly whether an advertised discount actually beats the real average for its category — based on thousands of verified deals, not marketing claims.
Category averages update automatically as new deals are verified. Overall average across all categories: 40%.
Retailers know a big percentage looks impressive. But a "50% off" on a category that routinely discounts 50% is just a normal price — while a "30% off" on a category that rarely drops below 33% is a genuinely strong deal.
This tool compares the discount you found against the real average discount for that category across thousands of verified deals on WhatNotSell. Instead of guessing, you get a data-backed answer: is this actually a good deal, or are you being shown an inflated number?
