I too have been burned by sellbackbooks.com. I sent my books around Dec. 12th and haven't received a thing. My status still says submit. Someone does email me on occasion and says that she will turn my order in to the warehouse but doesn't know if my books are there. I sent mine with delivery confirmation to the P.O. Box they stated. I sent 19 books!!! Anyone have any ideas? I will lodge a complaint with the BBB. I hope to see them in court one day soon.
