I agree with the terms of the expiration date period, if one is listed for my purchase. I also agree that in any event if I fail to show up for my scheduled appointment and or cancel my appointment without giving 24 hours notice that is considered a NO SHOW appointment. In such an event, you will loose that session as a part of your package, it will be deducted from your package and or if you use a gift certificate that GC will no longer be valid for use in the event that you fail to show up for a scheduled session or cancel a session without giving 24 hour prior notice..
