The answer to, ‘Can you return Kindle books?’ is yes, technically. However, conditions are applied, and whether you can or cannot perform this action varies based on several factors.
The important thing to know is that you can return a book you accidentally bought that is poorly edited and formatted within 7 days of purchase.
Amazon’s return policy
You can return a Kindle book within 7 days of purchase. The money will be refunded to the payment source within 3 to 5 business days.
Here’s the catch. Amazon retains the right to refuse a refund or may pay a partial refund if the book has been partially or completely read. They can deny the return if they suspect a user misuses their policy by returning multiple books.
