I did this for my Wii. I got a $20 coupon book; a $9.99 per month subscription to Rhapsody; a $5.00 per month CD club subscription; and four inkjet cartridges for $20.
The site was "everyfreegift.com." I called them (that's right, make sure to get a phone number, they don't answer emails) to make sure it was legit. They said I could cancel the subscriptions after making the initial monthly payment.
So I did.
I still paid full price for a Wii on launch day, but a few weeks later got a check in the mail for $300. I don't think I would have gotten the check had I not called them about once a week after the Wii launched.
My End of 2008 Hardware Predictions (console only):
Wii : 50 million
360: 28 million
PS3: 24 million
These predictions were made on January 3rd and won't be revised
