I found this Instructor's Edition (ISBN 978-1-4641-5949-7) in a hallway on campus. It is the same text as the student version (ISBN 978-1-4641-8945-6) but it has the words "Complimentary Copy - Not For Resale" printed on the top of the front and back covers. The book is new, NO writing, NO highlighting, and NO underlining. Shipping typically completed via USPS Mail.
