Class Packs allow the flexibility and convenience of purchasing multiple spots in a class at a discounted rate that are not tied to any specific date.  This can be a great solution for families with more unpredictable schedules since these spots can be applied to any of the weekly sessions of a class that have openings. Once purchased, customers can register for an activity and the spot will automatically be deducted from their class pack balance.  However, these spots do expire and must also be redeemed within a certain time frame, and any unused spots are not refundable.  Spots can be used to schedule a class that occurs after the Class Packs expiration date,  they simply must be assigned to a date before the expiration.
