You are asking people to turn over personal info based on 1 vague line about discounts up to 80%. I think you need to provide a good bit more info- why does this free membership save me money? are they going to send me ads? etc etc etc.

Good points, thanks. Will include link to privacy policy and elaborate more in description. Was trying to cut down the copy to a minimum but I guess I went too far.
