If you’ve already finished your copy of Fifty Shades of Grey, consider selling it to Amazon.com for free Amazon credit and gift cards. I’ve used Amazon’s textbook buyback–which is open to all books, not just textbooks–dozens of times and it’s worked great every time. Here’s the how-to:
1. Visit Amazon’s textbook buyback page and enter your book’s ISBN number, often found on the back cover near the barcode.
2. If Amazon is buying the book, it’ll show you the Trade-In Value. If it’s not (for example, if it’s not in demand, too old, a select paperback or sometimes self-published), it’ll say Did Not Match Any Products.
3. When you’re done entering books, click Submit and Select a Shipping Method–best methods are UPS via pre-paid label or USPS. Package your books in a box, adhere the shipping label to the outside, and voila!
4. In about 2-3 weeks, your Amazon credit will automatically be deposited into your textbook buyback account.
