Win gift cards and other perks with Swagbucks
If this sounds like a gimmick, you've got a healthy amount of skepticism. The thing is, I've earned enough gift cards to sustain my Starbucks habit, order books from Amazon once or twice a month, and have Swagbucks leftover for iTunes and Target gift cards. If you sign up and don't like it, you can always un-install Swagbucks.
There are many other search-and-reward programs out there, such as UPromise and MyPoints. I've never used either of these, but am curious about how they compare.
Signing up supports WalletPop.
