Ah, I see - I was looking at the FAQ entry on <a href="http://twitalbums.com/learnmore.html" rel="nofollow">http://twitalbums.com/learnmore.html</a>.<p>I appreciate the compliment! But all credit should go to joshu for that pricing model.<p>For what it's worth, I think payments are one of the most painful parts of an app to work on.  Any bugs catch people at their grouchiest moment (handing over money), and the available payment options all suck in various ways.<p>Best of luck to you guys!
