9 out of 10 times, those online coupon finders never worked. You needed to use them pretty much on the day they were posted to the site, otherwise there would be too many redemptions by the time it found it ranked on Google search.
Today it is pretty much actively a scam and you are better off searching for a newsletter subscription that often come with a 15% off code etc.
(I assume the mechanism here is to obscure the coupon enough that Amazon doesn’t get mad you’re selling under their pricing but you let the customer have some of the savings from avoiding Amazon’s commission.)
