Amazon does buy back used books, but it’s not a straightforward process. Amazon does not offer a service for selling used books directly to them.
Instead, Amazon allows third-party sellers to list used books for sale on the Amazon marketplace. These third-party sellers can be individuals or companies that specialize in buying and reselling used books.
In order to sell used books on Amazon, you must first set up an account as a third-party seller. Once your account is set up, you can list the books you wish to sell.
You will need to create a listing for each book you wish to sell. In your listing, you will need to provide information such as the title, author, condition of the book (new or used), and your asking price.
Amazon also has its own program called Amazon Trade-In that allows you to trade in eligible items in exchange for an Amazon gift card. This program allows customers to send in products such as textbooks and electronics in exchange for an Amazon gift card worth the estimated value of their item. Unfortunately, this program does not accept books.
Conclusion:
Overall, it is possible for individuals or companies to sell their used books on Amazon by setting up an account as a third-party seller. However, there is no direct way to purchase used books from Amazon itself and its Trade-In program does not accept books.
