lockerz.com is the website, its invite only but I have a few invites.
Basically everyday you you check the site and answer a question in there blog(like what kind of music you like, is you job ideal, etc..) and you get 2-10 points depending on the day. And then you can use the points to buy stuff. 100 Points gets you a video game and you can also get game systems, I've just used it to get video games...
If you want an invite I have a few left just post your e-mail here or pm it to me if you don't want it on the forum.
