You will be given a COUPON code and the instructions on how to use it to book your appointment online.
To get the full value out of your Groupon, you must redeem it before it expires (even if the appointment itself is for after the expiration date). So don't wait till the last minute, redeem your Groupon today.
PS: If your Groupon expires, don't worry, the amount you've paid can still be applied towards the price of any service with us.
Just for today, don't get angry, don't worry, be grateful, do your best, be kind...
