Bing has a rewards program that gives you free money for doing something you do anyway: use a search engine. And you can redeem the points for some good stuff including microsoft points, hulu plus subscriptions, and gift cards for restaurants, stores like Amazon and Target, frequent flyer miles, and even gas. It's like the early days of internet shopping all over again. You can get something for nearly nothing. And if you're not happy with the bing results, just google it.
