“On the whole, the problem with new books is that there’s a list price set by the publisher and a discount price that’s also set by the publisher. So, as a new bookseller, you have no control over what the book sells for or what you pay for it. With used books, if you’re smart, you find ways to get them cheap, and you decide what you price them at.”
“As a general rule, on any book, a used bookseller is probably making twice as much profit as a new bookseller. And that’s the difference between making it and not making it, because the profit margins on new books are razor-thin. At a used bookstore, no one is getting rich, but you can make enough to stay alive.” – Benjamin Friedman, co-founder, Topos Bookstore Café, as quoted by The Awl.
