I sent in a valuable hardcover book that included an author signed card. They said the cover was damaged! It was slightly used (it was a vintage book about Bergdorf's window dressings!) but not damaged and they offer you no dispute. They can arbitrarily destroy your books with no proof of damage, and when you try and complain to customer service they tell you to read the terms and conditions. Besides that, they also didn't honor another book and labelled it "Expired". What does that even mean? Don't use them!
