I don't know about you but I am going to shop, I'm going to buy stuff on line and I'm going to spend money. But, just because I'm spending money doesn't mean I don't try to save as much as possible and cash back is certainly one way.
Take for example Ebates -- Ebates is a company that once you sign up you log in, visit their site for a cash back reward and then use their link to get to your shopping site. I'm a student, so every year I do a google for the lowest price of my book, then I do an ebates search for that company and compare the cash back value for that site.
