The biggest problem I had with POD books was getting bookstores to carry them! I think I was only able to get one or two stores to actually order the books from the publisher. The rest took about a half-dozen on consignment, I forget the percentage. And I had to pay around $10 each from the publisher for each copy of my book...so basically, if I wanted to break even, I'd have to price the books sold on consignment at over $20 just to break even--and these are trade paperbacks. I saw that no matter how many books I sold, I'd never be able to make any money off them selling them in bookstores. I could only make money selling them to random people I met...I had a website up at one point but I only sold a couple of books through that, too. Finally I just said "screw it" and am now trying to go the traditional route.
