If you haven't heard Ebates pays you to shop. My total Ebates cash back is over $700 Lets say I need to buy some tires for my car at Pepboys. I get on Ebates and search for Pepboys then follow there link to the actual Pepboys site. Anything I now purchase I earn cash back usually around 2-5% depending on the store.
Every quarter I recieve a check in the mail from them. Or you can get paid via Paypal or Amazon gift certificates. Ebates even has coupons listed on there site for even more savings. There is no excuse not to use Ebates unless you hate money. Even if I was as rich as Bill Gates i still would use the great site.
