Yeah. I've been ordering a lot of books from the early 80s to mid-90s of late, and have learned that Discover Books and their affiliates sell books in poor condition. This would be fine if they were honest about it, but they're not. Each and every book I bought from them was in poor condition, but across the board Discover and their affiliates rated them as "very good" and charged accordingly. I've included two photos of books I've received from them. The one with the broken spine is "Emprise" by Michael P. Kube-McDowell (the exterior spine is so creased you can't even make out the title information). The other is "Orphan of creation" by Roger MacBride Allen. Really, they described a book with huge chunks missing from the back cover as "very good."
Because they have so many affiliated fronts, they can pull fast ones. I have a working list of store front names they use, but they most reliable way to spot them is to check the seller on Amazon. Clicking on the dealer's name for any given book will bring you to the "about page" where the seller's name and details will be listed. Discover Books affiliates with have the "Discover Books" logo just to the left. That's the third picture.
