I'm not sure if you have heard of this before, but I have been hearing good things about swagbucks. This is a search engine where you earn "swagdollars" just by surfing the internet (something you're gonna do anyway). Once you earn enough swagdollars, you can turn them in for real life prizes. For instance, with 50 swagbucks, you can purchase a $5 Starbucks GC.
