Keith, yes sir, just add the firearm to your cart and proceed to checkout. When you get to payment options just click on 90 day layaway plan. On the next page it will allow you to add your gift card code. If you already put the firearm on layaway and are just trying to make a payment I'd recommend contacting buds customer service at 859-368-0371 Monday thru Friday 9am to 9pm or you can use the blue chat button at the bottom right corner of your screen. They'll be able to assist you in making a payment using the gift card. We're just customers as yourself not buds employees, so we can only point you in the right direction. Hope this helps.
