After you've set your Gift Card option in your E-Commerce, you'll need to set up a page on your Builder to display them.
First, click on the Builder icon and then the web pages tab. From there, click on new page and then gift cards.
This will add a new Gift Card page to the bottom of your list of pages. You can rename the page using the pencil icon and reposition the page by dragging and dropping it.
On the gift card page, you have the ability to add some text that will appear above your gift card options to explain your gift card policy or recommendations as needed.
Make sure to click on save changes after you add your text.
You can also add HTML code to the bottom of your page if needed.
