I have purchased books from them before and no problem. This past time however, I never received one book from the order through their seller Owl books. I have contacted both the original seller, Abe books and the bookseller Owl books numerous times since April 20/24 when the book was to arrive. Nothing, no feedback whatsoever. I have a feeling I am out $20 US and will never receive my book. I will never purchase anything from Abe books again. Ever!!
