I bought a book via Amazon Marketplace. I never received the book. I called SuperBookDeals, and had to speak with a very rude woman. Eventually, she told me that the inventory was empty. I asked her why they could not do me the favor of letting me know in advance. The woman then yelled at me, and when I asked to see the supervisor, she hung up. I am still waiting on a refund. I received an email promising a refund but I am still out a bunch money. Do not buy from this seller!
