Have you tried Swagbucks yet? It is search engine that works just like google or yahoo, with the exception that you can win free gift cards just for searching. Swagbucks.com awards swagbucks that you can exchange for gift cards and such. I currently have over a hundred dollars worth of gift cards stashed away for Christmas just from using Swagbucks! It only takes 450 to earn a $5 Amazon gift card.
You can get a great start by signing up with Swagbucks now. Just for signing up (for free by the way) you earn 30 free swagbucks and if you enter the code BackToSchool in the "enter your swag code" box you will get another 40 swagbucks for free!
Thats a total of 70 swagbucks for doing nothing at all!
And Thursday they will be releasing 5 swagbuck codes to give you even more free swagbucks!
