Many college bookstores allow students to sell their books back to the stores. These used bookstores pay around 50% of the original price to the student for these used books. The price could vary though, depending on the book. The used book store market follows a fairly complicated business process. Once a student sells the book back to a college bookstore, it is then re-sold to a national used book company. The same book is then sold to another college bookstore, at the end of which the book is available at a price that could be around 75% of the new book price. During every step of the process, a margin is applied by each of the respective parties to gain profit. This typical business cycle allows everyone in the chain to make money and be in the business. Though the sellers have margins during every step of the process, used books are still quite a bargain when compared to the price range of new books.
