I ordered two books for medical administrative assistant classes and first time I ordered them I was refunded my money back by Abebooks for one book probably because the seller didn't have it. I was sent an e-mail stating that I was refunded the same day. Luckily I was able to find the same book for a little cheaper. Both books shipped very fast definitely less time than was estimated. Only thing that bothered me was that I was not given any tracking numbers to track my books but that didnt seem like much of a problem since they came so quickly. I don't really have any bad to say about this website.
