BUYER BEWARE. You can not sell this book back

The product i received was not the student copy of the book, but instead the instructors copy, and while I did not see a problem with this while taking the class, upon trying to sell the book back at the end of the semester I found out that these are never for public sale and has ZERO resale value. The seller had taped over the not for sale marking on the back of the book.
