Check this out. I just registered with something called "Swagbucks", a search engine site. One earns points for doing searches just like at google or ask.com, etc. Once one reaches a certain number of points, he is eligible for gift cards. I learned about it at a money saving blog I read frequently called Money Saving Mom.
