No they are fake! They are just a figment of your imagination. They are real and some can be quite rewarding. To piggy back off of frank, with NPD Research, the prizes from the contests are great but even better the info you put into the survey gets sold to companies in different industries. If the companies are smart they will use that data to change their products or services. I think its cool
Don t bother. The things you get are stupid...like subscriptions to magazines you would never pay for anyway...I would say NO.
They are not real. They are there to scam you out of your money.
