For those types of offers, you must take part with their sponsors first, that's how they get the money to get the Mac Book or whichever prize you're trying to get. They often show lists of different offers from different companies, not usually free, but ones such as ex: Book club, sign up for only $3.99 and get 3 FREE books. It'll cost you $3.99, and however much the membership fee a month, but it counts for you. The may ask for any number of offers to be completed, but you have to watch out; most of these places will try to bill you without you knowing. So if you think you want to try this, I'd suggest using a pre-paid credit card. I did, and I got about 20 charges for $8-20 in the first 2 days. I only had it loaded with about $2 just in case. So if you think you want to try it, just be warned that it is kind of sketchy, but people have proved it to work. Good luck!
