How is the balance on the Gift Card calculated?

If you make a purchase with the Card, we will deduct the full amount of that purchase, including taxes and any other fees, from the Available Balance. Once the Available Balance reaches zero ($0), the Card is no longer valid and you agree that you will no longer use it. However, if a transaction occurs despite an insufficient Available Balance on the Card, you agree to reimburse us, upon request, for the amount of the negative balance created on the Card.
