I have bought dozens of books from AbeBooks. Some sellers are wonderful, most are just fine, but a few are fraudulent. Unfortunately, there is no way to leave a review to help others sort the good from the bad. They do have star ratings showing percentage of sales without returns. However, this leaves one in a position of paying to return a poor quality book to be resold to some other unsuspecting book buyer in order to make sure the seller's star rating is impacted, or tossing the book thus leaving the next buyer having no idea that the seller is misrepresenting their merchandise.
