To redeem a gift certificate, simply shop for the products desired and proceed to checkout.  After entering your customer information, at the bottom of the page you will find a prompt for "Gift Certificate Code".  Enter your code and continue with checkout.  If your purchase amount is less than the value of the Gift Certificate, the difference will remain in your account and you will be able to use the remainder at a later date.  If your purchase exceeds the amount of your Gift Certificate, you will be prompted to pay the difference as you continue with the checkout process.  Please Note: Gift Certificates expire twelve months after their original purchase date.
