Swagbucks is an online search engine powered by Google and Ask.com. When searching online you can win Swagbucks, usually 1-5 bucks. Once you accumulate only 45 Swagbucks you can redeem them for a $5 Amazon gift card! There are lots of other prizes too! If you search online as much as I do then your Swagbucks will build up pretty fast.
There is another way to earn even more Swagbucks: refer your friends. Whenever you refer someone you will earn a Swagbuck every time they win a swagbuck!
