You use just like you would any other shopping search engine to find the right product at the best price. But when you actually buy something from a store in our engine, we share at least half of what we earn by connecting you to that store. All you need to do is sign up for an account to earn cash back. There are no fees or hidden charges.

Seems to be a cool way new of comparison-shopping. Did you try Jellyfish yet?
