Their mission at TextbookX is to find students the lowest prices for their course materials. They do that by offering a mix of our own inventory with that of third-party sellers in order to provide one of the largest inventories of new, used, digital, and rental books.They don't just supply textbooks, though. Through us, students can shop for other school supplies, best-selling books, magazines, study guides, and more. They also host a large Marketplace, where third-party sellers and students buy and sell their books year round.
