Watch out for the rip off.The instructors edition is 27 pages and not 272 pages.The adds will say "paper back 2.6 ounces"The 27 page rip off edition weighs 2.6 ounces.When I complained about the rip off, they said, "When the returned item(s) are received and processed, we will issue a refundto the credit card number submitted with this order for the product price ofthe returned item(s), not including the shipping and handling."I am just going to chuck the instructor's edition in the trash and chalk it up to internet rip off.
