Have you heard of Swagbucks? It's a search engine (like Google) which allows you to earn points for searching. Your points, or Swagbucks, can be redeemed for prizes like gift cards to Starbucks and such. You just download the Swagbucks toolbar, use it as your search engine, and start earning points.
I've had a link in my sidebar for a while now, but kept having people say "Have you heard of swagbucks? I just signed up!" Then I kept responding, "Oh! You should of signed up through my link!" Then they would say, "Oh! I wish I had known; I totally would have!"
So, now you know. If you are interested in using Swagbucks, sign up here!
