No, I don't need to precommit. There is nothing really preventing me from doing this. I want to say yes to this experiment, but immediately come up with more stuff that this would require that holds me back from adding it right now. With tiers you will eventually have people who want to upgrade / downgrade between the tiers (of course I can just say you can't do that). I need to change my scripts that scan PayPal to support these tiers and still correctly figure out who to send to. Need a tier selection page and this will also complicate wording on the main page. Not missing out on those customers who only wanted one envelope a month seems it might make this worth doing, agreeing with you there and hoping to find the time to add this.
