I entered my ISBN number from the books I wanted to sell, it gave a price, I shipped the books, then I received an email stating that they would not buy my books because they were instructor editions! They are NOT instructor editions... they are exactly what the ISBN number says they are... student editions. Then, I had to pay for shipping to get my books returned! Total scam company... don't bother doing business with them... they SUCK!
I'm sorry you weren't happy with the service. An instructor edition can look almost exactly like a student copy. It will just say instructor edition or do not sell on it. A lot of companies will print student isbn stickers and place them over the info that shows it's an instructor copy. We only ask that you pay for return shipping if you send us one, because we lost on the shipping getting the wrong book here. Thanks
