When you have chosen what books to sell, you can receive payment in the form of a check or via PayPal. Another great thing about this service is that you can recycle your books which is good for everyone. Plus, you don't have to pay for any of the shipping costs for any books that you sell to this company. If you are selling 5 or more books, you can send them via FedEx which means that you will receive your money sooner. If you have less than 5 books, you can send it for free through the post office.
