Therefore, once we get your order, we send electronic search lists to used book dealers daily for what we don't expect to get in buy back. That means, the sooner you turn in your adoption, the greater the probability is that we will be able to get used books for your students. Many students shop early for their books. Many of them are trying to get a head start on their studies. Others want to buy used books before they are sold out.
Publishers can and do run out of books.
The later we receive an adoption the greater the chance that it will be out of stock or backordered by the publisher. We also purchase books back from students that were used in previous semesters. Often we turn right around and order them right back at a higher price once we get your adoption. Shipping costs are lower when we order more books from the same publisher in the same shipment. Lower costs go hand in hand with lower prices.
