Yes and yes! You can purchase a gift card for either a specific service or package, or for a dollar amount, it is completely up to you. If you are not sure what services someone would want to try, a dollar amount allows them to choose their perfect way to be pampered.
Additionally, if a gift card is purchased for a service or package, it still holds the dollar value of that package or service, so if someone decides they would like to do a different service, the value of the gift card can go towards whatever they decide to book.
All in all, you can't go wrong with giving the gift of relaxation!
