RentBack makes you money and puts the textbook market in your hands like never before. With RentBack, you can send the textbooks you own to our warehouse using our free shipping labels. We’ll rent them to other students, and pass the profits from those rentals to you. Your single book may rent multiple times, and we’ll pass the profits to you each and every time. We’ll put our warehouse, technology, shipping contracts, textbook data, pricing engines, marketing expertise, and distribution channels to work for you. You send the books to us; we manage 100% of the process and send you the cash each semester. We’ll even send your books back to you when their useful life ends if you wish. We’ll take a small and very transparent fee, but that’s it.
