The companies that do this, there are at least 2, get paid for getting people to sign up for stuff, the one you are talking about is the worst because you have to recruit at least five people to sign up for at least 2 offers each, the other one it is just you, for the lesser prizes you can enlist into things like a dvd of the month club or a Blockbusters rental plan, to get the better prizes you sign up for a different calling plan or credit card, that type of thing. If you are going to do that anyway then why not get the freebies but if not I would not do it.
