We were inspired by something John Buckman is doing at the online record label Magnatune. When you buy a CD, Magnatune asks "How much do you want to pay?" and gives you a price menu. You can't pay nothing, but you get some latitude. You can low-ball them a bit, or, if you're feeling grateful, pay more. It sounded like a fun idea to us. We've had people—and not a few—pay twice to thank us. But we've also had emails from people who say they'll buy a membership next time they get their pay check, disability, etc.
