I am still waiting to receive a book I ordered months ago. I have sent multiple inquiries about my order, but still no response after two weeks. The inquiry form even promised a response from customer service within two days.
This once-reputable site has turned to bait-and-switch promotions and discount offers that turn out you can't make work. They are not good guys. They have retailer bookstores at their mercy, although almost no retail store likes them or their predatory practices. See what the store has, and try to buy the book direct, if you can. Otherwise, caveat emptor.
