Allows you to attend 4 classes in a month. A 3 month commitment is required. Your credit card will be charged $45 on the same day every month. (For example, if you purchase your pass on January 5th, you will be billed again on February 5th and March 5th.) If more than 4 classes are taken in any of the 3 months, your card will be charged $11.25 for each additional class taken (the same per-class rate you pay for your 4 class auto pay package).
