The Couples' Discount We offer a couples discount in the online class, where one person attends as a student and the other person audits class. But beyond our pair discount, we are counting on each additional person attending class to sign up and pay a class fee. We are trying to keep the class tuition low (it has not been increased in a decade) but we will not be able to continue to do so if friends and family are invited to watch class for free. The Couples Fee One new student ($180) and one auditing ($45) for a joint class fee of $225 or One repeat student ($125) and one auditing ($45) for a joint class fee of $170 A couple must attend class on the same day and only the student gets a personal weekly check in from Kathy, and only the student gains access to password protected parts of the TQI Diet website.
