About 80% of regraded books are cancelled by the buyer. Since buyers are disappointed in receiving a book not in the condition they originally ordered it in, we allow only buyers to decide on whether to accept or cancel a book once it has been regraded. On their order page, they need to click either the Accept or Cancel button next to the regraded book in order to unsuspend the order. If the buyer has not responded to the instructions from Atomic Avenue, and you have also contacted the buyer by email and phone, and there is still no response, remove the book from the order and ship the rest promptly. Odds are the buyer would not have wanted the regraded book, and it's not wise to hold off on shipping the rest of the order waiting for an unresponsive or indecisive buyer. If you believe the buyer would accept the book in its new grade, do make every effort to reach the buyer via email and phone to get a response in a timely manner.
