You can redeem a gift certificate two ways:
Give us a call and when you are placing your order, let us know the validation number of your gift certificate. When your order is processed it will reflect the new reduced total.
OR
While shopping from our website, when you proceed to checkout, make a note in the comment box that you have a gift certificate and write down the validation number. This way when we process your order, the gift certificate amount will be deducted from your order total.
