During the week of final exams for every semester we conduct a book "Buyback". This is when we buy your used textbooks if we need them for the following semester. We usually offer anywhere between 0% and 50% of the purchase price if you purchased it from the LLCC Bookstore. You do not need a receipt for buyback. If we do not need the book for the next semester, a wholesaler is working with us to purchase your book if it has wholesale value. It is your choice to sell your book at the offered price at buyback or to keep your book as long as you purchased it. Other options to sell your books include using the "Campus Marketplace" on this website. There you will be selling to other LLCC students. You set the price and the exchange. Don't wait too long to sell your old textbooks. Publishers change editions very frequently and the value of that textbook could go to zero very quickly!
