I emailed the instructor to see what book we were using, and I went on EBAY and found it $100 cheaper, plus the seller dropped in the workbook which our program didn't require (all classes are different) but it has actually been a great part of my succeeding in the class because. So check EBAY. I'm sure a lot of us here have used different books and different editions of the same book. Check with the program instructors first.
