If you like Ebates and Cashbaq, you should try SwagBucks, which gives you "bucks" for online searches you do through their search engine. Bucks will get you gift cards and other prizes.
1. Sign up free at SwagBucks.
2. On their site, click "Toolbars" and get one of their toolbars to show up on your browser.
3. Do all your searches on that toolbar. You can do shopping through there too if it's not worth it to go through ebates or cashbaq. The bucks add up pretty quick. At the rate I go, for normal searches I do, I earn about one $5 Amazon gift card a month.
