I got my first Mac Mini, iPod Shuffle and PSP through these.
How it works is that you sign up, complete an "offer" (almost all used to be free trials that try and make it hard to cancel). Your account has a referral link and you give that out to sign people up under you. They sign up and complete an offer and it helps you. You have to get a certain amount of referrals based on the cost of the product.
The reason these things work is because many people don't finish, so the company makes money off of those who get halfway complete.
