I had this add-on for a bit, removed it shortly because I realized it didn't give me actual good discounts and that I could find much better ones manually myself (especially for big name shops and companies). I thought it made its money from tracking and selling your data, but it turns out this is a surreal level of scamming.

It essentially gets a commission or steals a commission from whoever gave you an affiliate link (which is why even if it finds no coupon codes it gives you a nonsense notification to press on), and also makes deals with big companies to only give you low discount coupons and meanwhile gives you high discounts on smaller companies that dont collaborate with them in order to get them to collaborate.

Crazy shit. The fact that this is a "legit" company is insane.
