We buy used text book year-round during our normal business hours. Visit us in Clark Hall on the main campus of Queen's University. A map to our location is available here. We understand that your book is used, however please be sure that your book is in reasonably good condition. e.g. no excessive highlighting, no missing pages or covers, etc. Finally, be certain that the ISBN of your book matches the ISBN quoted on this page. We only buy book back when the ISBN's match.
