My friend tried this and actually got a prize, so I figured I'd give it a shot. Most of the offers are free and just require filling out a form or something, so we'll see how it goes.
If anyone's interested, please sign up under me so I can get some credit. Definitely check it out if you're into games as you could very well end up with something for free.
