The Proof

The points you get on Points2Shop can be redeemed for Microsoft Points but you can also use them for a bunch of other prizes. You can get Gift Cards, Games, Cash, or you can use them to order anything from Amazon.com. Here's just some of the things people have gotten from P2S. There's also a live Shoutbox full of people currently using P2S on their website. I'm sure they'll be glad to tell you what they've gotten.
