Free add-on for the official <a href="https://woocommerce.com/products/gift-cards/" rel="nofollow ugc">WooCommerce Gift Cards</a> extension that allows you to use the default coupon form to apply and redeem gift cards.
After activating the plugin, the “Have a Gift Card?” form will be hidden, and customers will be able to apply gift card codes using the coupon input field.
Note: This plugin has been created to validate and refine a feature that may be rolled into WooCommerce Gift Cards — or dropped! — in the future.
Important: This plugin is not compatible with the Cart and Checkout Blocks.
Important: The code in this plugin is provided “as is”. Support via the WordPress.org forum is provided on a voluntary basis only. If you have an active subscription for WooCommerce Gift Cards, please be aware that WooCommerce Support may not be able to assist you with this experimental plugin.
