For most of the products and programs we sell, we offer research into the effectiveness of the therapies that each product represents. Some people find it helpful to do additional research on their own, and the literature represented here offers some of the best work on those subjects.

In an effort to offer the best prices available, we have partnered with Amazon.com. Pricing may vary at Amazon as they changes prices daily in an effort to have the lowest prices. Just click on the books below to view current Amazon pricing.
