Someone told me about Ebates and I signed up just before starting my Christmas shopping (which I did a ton of over the weekend) and so far I have $15 pending from just 3 stores. They'll send it to me as cash back just for going to the shopping websites using a link on the Ebates website. I also got coupon codes to use in checkout that saved me even more money.
The cash back percentage is different for each store, but it adds up quickly. I did nothing and I got $15 in return just for going to a website and using their link to the store. Love it!
If you sign up, please do so through my link here so I get more cash back for referring you. Thanks!
