If you look at the buttons in my sidebar, you will find one for Swag Bucks. I heard about them a long time ago, but didn't really look into it until a few weeks ago. Basically, it is a search engine, but you earn points randomly for searching. The points can be redeemed for gift cards and other prizes. I am getting close to having enough points for an Amazon gift card, and several bloggy friends of mine have gotten literally hundreds of dollars worth of gift cards this way. Why not get paid for something you're going to do anyway? Today is Swag Bucks' second birthday, and they are doing some fun things to celebrate (like giving out lots of points). If you haven't signed up, go on over and check it out. :)
Another way to earn points is by referring friends. So, when a friend signs up using your link, you would get Swag Bucks when they do (up to 100).
