I placed on order for my textbook. I verified that the textbook had the same ISBN that I needed and that it did not have any wording that said it was an international book. However, I received an international edition. I could not use the book. I requested a return which was approved but I had to pay shipping which cost me $24.50. Apparently the checkout page says they are selling international edition and you must confirm that. I didn't realize this since it was the same ISBN number that I needed on the order (book received was different ISBN). DO NOT BUY FROM PRIORITY TEXTBOOKS, CHEGG IS A MUCH BETTER OPTION.
