I haven't used the app store in several weeks but as I recall, when I want something in the app. store I just hit the "give 'em .99 cents button" and it remembers my cc info and gives me the game. Are there any payment processors that can make this kind of system work? I'm looking for a micro-payment system that doesn't take a minimum $ amount per transaction so I could go really low. Any ideas how to accomplish this?
