Abe Books is not a bookseller per se but instead an Internet umbrella organization linking many independent booksellers. If you have any problems whatsoever, Abe Books will only direct you to deal with the underlying or networked bookseller you purchased from. In my case, I ordered a book and paid for the "priority" shipping. Book never arrived and upon contacting the bookseller, was told they had no way of tracking it! Again, Abe Books would not help, they only direct you back to the actual seller. Will never use Abe Books again. Am still trying to get a refund...
