 We purchase our books for resale so most of them will have old price stickers on the back cover. We do our best to give an honest description of any damage to the books, but what we sell are used books and we have no idea the history of the books.

When we list a set of books they are boxed and sent to our warehouse to await sale and shipment. It is not cost effective for us to bring them back to our office and sell just part of a set.
