COOL NEWS! We have a brand new Instructor's Guide (8th edition) that was just released two weeks ago. It has many amazing new sections and updates (over 150 new pages, too). Now would be a great time to receive it. We can send it on 60-day review if that makes it easier for you to arrange payment later. We will follow up with you in regards to this offer in more detail if you provide your mailing address below (most provide their home address which we never share with anyone).
