I use a search engine, swagbucks.com, which is powered by google & ask.com. Every now & then I get a "swag buck" for making a search. These are redeemable in the "swag store" for all kinds of stuff, but I've just been getting $5 gift cards to amazon.com. I'm up to $35 in amazon.com gift cards, which I plan to spend on the kids for Christmas this year. (Amazon has some amazing deals on toys around the holidays, like 75% off!!!) Anyways, just thought I'd share the find! It's free, you don't have to download anything, you get the same search results as you would with google or ask, plus freebies!
