Swagbucks is a search engine where you can win 'bucks' for each search accumulate 'bucks' and you can trade them in for my favorite... Amazon gift cards. I've won about $25 worth of amazon gift cards since I started. Right now I have enough swagbucks to turn in to $10 Amazon gift card but I'm holding out a little bit. I just use Swagbucks as my search engine.
Check it out, it doesn't cost you anything. You basically get free money just for searching the web, which if you are like me, I do it all the time!
