Be rewarded for searching the internet. Yes, that's right. I currently use SwagBucks as my search engine, and in return I get swagbucks. These 'bucks' allow me to purchase a variety of stuff from their store including: Xbox 360, iPhone, PS3, guitars, even gift cards.
I'm actually saving up right now to get a $50 Best Buy gift card that requires 500 SwagBucks. So far after 9 months, I'm been able to obtain 345 SwagBucks.
Signing up is fast, easy, and they don't send you any bogus emails from their partners.
