Hi Sean and welcome. The method is to checkout as normal - enter FFL if a firearm - click "continue to payment method" - click confirm address - select the Credit Card/Gift Card payment method - enter Gift Card code and click validate. The amount will be deducted from the total. If you have multiple Gift Cards, just repeat entering another code and validate again and the amount will reduce. You can do this for as many Gift Cards that you have and finish the checkout process. Cheers, stay safe and enjoy!

Hi Sean, during checkout, choose 'Credit Card/Gift Card' option. Then at the bottom of page click 'Continue to Order Confirmation'.
On that page you will see a box to Enter Gift Card Code, once entered hit the Update button. If you have more than 1 gift card you can do this multiple times.
