Booksellers are required to accept returns for all reason except when the buyer changes his/her mind. Note that laws in certain European jurisdictions may require some European booksellers to accept returns regardless of the reason for the return. Most booksellers find it to be in the best interest of good customer service to accept and process returns for ¿buyer changed mind¿. Buyers are advised they must reach an agreement with the bookseller for the ¿buyer changed mind¿ before returning the book.
