Swagbucks is a point earning site, where you can trade in your points for rewards. You earn points by doing something you do every day, searching the internet. Instead of using google, you just use their toolbar and you can earn points with any search.
The best rewards deal I've found on their site, is when you reach 450 points, you can trade them in for a $5 Amazon gift card. I've been a member of Swagbucks for about 3-4 months and have already earned 5 gift cards. You can use multiple gift cards on an order too, so just keep saving up your $5 gift cards until you can get something you want.
Friday's are Mega Swagbucks day, so you're even more likely to earn big points today. So, if you haven't signed up for Swagbucks, now would be the time!
