Beware of all $1 to try programs. Usually these end very soon in a recurring billing. Adult sites use this trick since G*d knows how many years. The secret of this trick is an almost irresistible offer, with unnoticeable small print about the recurring billing part of the offer. Many of the enrolled clients forget to cancel the recurring billing subscriptions before it happens to see their card charged a few times. Hence this is the essence of the method, suppliers don't even bother to add valuable content to the subscription, but they add some quantity of crap just to say they delivered something.
