How we find and test coupon codes
This page explains where our codes come from, how we check them, and why we show a chance-to-work score instead of a flat "this works".
Where our codes come from
We gather codes from the places stores actually publish and share them:- The web, social media and search. We scan constantly for newly published codes.
- Store marketing emails. The codes stores send straight to shoppers.
- Affiliate and partner feeds. Codes sent to us directly by stores and the networks they work with.
How we test codes
Finding codes is the easy part. Knowing whether they work is harder. Some of the codes we list are tested in real shopper checkouts, so we can see the discount a code actually produces.Shoppers help too. After you copy a code, we ask a simple question: did it work? Every answer feeds into that code's score, the yeses and the nos.How we score each code
The same code can work for one shopper and fail for the next. So we don't stamp codes "working" or "not working". We show the odds instead.Every code has a chance-to-work score. A new code from a good source starts with a cautious estimate, and real checkout results and shopper feedback move it up or down from there.Older evidence counts for less as time passes. A code that worked yesterday tells us more than one that worked a month ago. And when we don't have much to go on, we say so.How we order codes
The codes most likely to work go first. The order comes from the chance-to-work score, never from which codes earn us money. More on how we make money.Why you won't always find a working code
Sometimes nothing looks likely to work, and when that's the case we tell you.Codes come with strings attached. Many only work on certain products, or for first-time customers, or for a short window before the store pulls them. When the odds are low, we show a low score. We'd rather tell you that than waste your time at the checkout.
