Do you publish on Amazon? If not, you are leaving a lot of money (relative to leanpub sales) on the table.

First, Leanpub allows you to simultaneously publish on Amazon or anything else if you wish. So... If that's what you want to do, you can.

I choose not to publish on Amazon because I have philosophical reasons for not wanting to do business with them. As it is my lifestyle hobby, I needn't worry about leaving money on the table. But if this was my business, that might be important.
