Couple other things - it doesn't seem to be deducting the amount of the certificate. I paid for that 3.99 item as mentioned above, and the only certificate I had was for 3.99. When I went to buy another item, it still told me I had 3.99 available in gift certs.

Also, since this is a non-shippable item, and I have checked the box to tell the cart that this is so, the Delivery pane shouldn't be visible - but I have a Delivery pane when I try to purchase a new certificate for someone.

And since it is technically not shippable, it tells me I need to select a shipping option before I can continue.

Just a few minor bugs, hope you can get 'em worked out! Would love to start using this
