Kickstarter

Because you're selling directly, and because you'r offset printing, the fact that you're not having to share a big chunk of the money with the amazon allows you to be able to give that discount while still covering the bills. When they check out through your cart, you have their email address, which means when the next book comes out, it's very easy to be, hey, here's the book. You sign up by such and such time to get the signed copy. The price is lower now than it will be on amazon later. And it creates that urgency in a really real and authentic way.
