Gift certificates are available in any value. You can choose to purchase your gift certificate for a treatment length (60 minutes) or for a specific dollar figure ($100).

When a gift certificate is purchased, the description of the service is “Gift Certificate” and the dollar amount paid is listed on the receipt. When the gift certificate is redeemed, a receipt for the dollar amount of the gift certificate is not issued. If the recipient of the massage wishes to receive a receipt, the dollar amount listed must be “gift certificate redeemed” with no dollar amount given.
