That is good to know..Thanks for all your comments. I didn't know about half.com. Will check it out. How does that work when you order used books from Amazon. Does it come directly from Amazon.com or from the used book store owner? Have you ever sold any to Amazon.com? A friend told me she sold some dishes back to them. I see on the website, that the used book store owner is rate for efficientcy and I noticed they grade the condition of the book.
