This service is being provided by a college student for college students. The entire purpose of this site is to give you (the student) the best possible price for buying and selling used books. The University Bookstore sells books for prices that is high and buys books back for low prices. Which is unfair to you, but at Kumars Bookstore you get to set the price higher than the University's buyback price but lower than the selling price. This way, both the buyer and seller wins.
