I've placed 2 orders so far. The prices and shipping times are very reasonable. Some bargain books may have a small dot with marker on the bottom of the book but some are completely brand new with no marks. I had an issue with one damaged book. I contacted customer service and got a response within 2 days for a replacement. So far, I am happy with my purchases and the service.
Tip for consumers: There is a loyalty points program and friend referral discount.
