The first book I recieved states clearly on the cover and I qoute "THIS INETERNATIONAL STUDENT EDITION IS NOT TO BE SOLD OR PURCHASED IN NORTH AMERICA AND CONTAINS CONTENT THAT IS DIFFERENT FROM ITS NORTH AMERICAN VERSION". This was taped over with blue tape so it would not be visible. The second book I ordered still has not arrived despite their claim that it would be here on time. Because of this I have had to pay full price for both books at the campus book store. If you really think it is worth it to save a little bit make sure you check everything out about the book you are purchasing (make sure it is the same cover as the one you are supposed to get).
