Several months back I brought in 7 books to sell. During the conversation I had with Ken Sanders himself he relayed a few of my books were worth something. Two were serialized, autographed WWII books. Two others were copies with rare autographs of a fantasy author. While he proceeded with the payment I didn't think to ask him how much for each. Thinking he would be fair and honest.
Before I continue let me caveat that Mr. Sanders is a professional is field. Highly respected and knowledgeable on the subject of books. Which is why I was surprised to recount the money in my car to find he gave me $35 for 7 books. Four of which he said from his own mouth were worth more than $100 each. When I went back inside he said no refunds or returns. We both got upset at each other and I left. The next day I called to explain the situation, thinking he may have been unduly distracted. Except the lady on the other end began to laugh and degrade me and accuse me of lying. DO NOT! I repeat DO NOT SELL BOOKS TO THIS ESTABLISHMENT. I even looked up the books my grandmother had me sell for her and sure enough one of the books I sold him wasn't available for less than $275 online. She was extremely disappointed as she needed the money for bills left over from my recent grandfather's passing. When she asked where the rest was I told her what happened. Needless to say it made my family very upset none of us have shopped there since.
