We apologize for confusion this might have caused - we simply meant a physical copy, but should have specified that the physical books will be paperbacks (the prices correspond roughly with trade paperbacks you'd buy in any bookshop). These won't be cheap books - we plan to make really beautiful paperback books and have a few particular models in mind from other indie presses already. But they will not be hardcover books.
(That is, unless we make more than $40,000, and hit a certain stretch goal, but I can't give any details about that just yet. Shhh, it's a secret.)
