A HELPFUL SUGGESTION: Before you e-mail or call us about an individual or group purchase (or how to access our online courses, assessments, and books once you've purchased them), please review our Frequently Asked Questions and Our Carefully Developed Answers. By first reading our responses to these questions, you might save yourself (and us) a lot of time. But if our FAQs do not answer your questions, then please contact us at your earliest convenience.
