To Redeem a gift certificate, select your products and fill-out an order form according to the directions.  There is a section titled "Redeem Gift Certificate" at the bottom left, fill-in completely.

When the order is processed the gift certificate will be deducted from the Merchandize Sub-Total.  Any unused funds on the gift certificate will still be available for use towards another purchase.  If your gift certificate does not cover the full order total, be sure to enclose additional payment.
