My school use to get the required books for our booklists from Endeavor books. Last time I used them, we ordered our books and about a month or so later we went in to pick them up. The line was huge and it took about an hour to get through it. They somehow always run out of stock and so I only got some of the required books with the rest to come much later. The prices are about average cost and not very good value. I don't recommend using their services again.
