You can use your Tru gift card at Qua for up to 25% of the cost of the service(s). You can continue to use your gift card in this manner until you have received the full value of the card.
Here is how it works: Say, for example, you have a $100 gift certificate from Tru. Assume you receive an $80 treatment at Qua. At checkout, you will use your Tru certificate to pay for 25% of the service ($20), and traditional tender (cash or credit card) to pay for the other $60. Qua will then issue you a voucher for your remaining balance of $80 that can be used in the same 25% manner.
