Different sites pay wildly different amounts for the same thing — one might pay £10 cashback whilst another pays £15. I like to make the most of things, and I got tired of opening ten apps to compare every time. So I built these tools. They check 30+ sites each day and show you which one is paying the most.
The links in this tool are refer-a-friend links — the same referral mechanic any user gets when they share their own code. When you sign up through one, the platform pays Scrimpr a small referral bonus, the same as if a friend had referred you. That's what keeps the tool free.
