As a user I think I'd like a model that works like some transit systems I've read about. Those transit systems sell per ride tickets for say $2, day passes good for unlimited rides for one day for say $10, and monthly passes good for unlimited rides that month for say $50. If you use their smart cards to pay for your tickets then they cap your daily spending at $10 (the price of a day pass) and your monthly spending at $50 (the price of a monthly pass). In effect they notice if you would have been better off if you'd have bought a day pass at the start of that day or a monthly pass at the start of the month and retroactively convert you to that.
