After I posted the percentage of the price of subscriptions and recurring payments that Clarkesworld receives, I was asked whether ebook sales were similar. Yes and no. We want you to buy where you like, but the numbers are quite different.
It shouldn’t be a surprise to anyone that ebook purchases of our back issues and anthologies yield the best returns when they are purchased directly from us. It is, however, the place where we sell the least number of copies. Amazon has the clear lead in that department with B&N a distant second, followed by Apple and Weightless (they keep swapping places).
