I heard about one from a rock station here in my town. I'll assume that thats reputable? In any case the url is
http://www.radiofreexbox.com I've looked at it but I didn't sign up. I figured if I heard a DJ give the site a plug, it must be legit no? Many have said it before though. In a lot of cases, you have to fill out information like how many people live in your house. The reason they use the xbox for example, is because they want to collect information about the people who would respond to that offer. It's all about marketing and statistics. Your info is worth a lot more than an xbox or an ipod. Btw the station is 100.7 (WMMS) Cleveland, Ohio
