Purchased 9 books described as in "very good" condition. Received dirty, torn, food and drink stained books some of which were ex-library and another the wrong book entirely; one of them even seemed wet. Contacted World of Books with details and photographs, they responded asking for "just two" photographs showing the condition. Sent the photographs and they responded saying that they would only refund one of the books, but I could return the others, paying the delivery costs, (which exceeds the cost of the books). Have contacted them multiple times since and have just been completely ignored.
