This plugin from Power Plugins makes it super-easy to add UK Gift Aid consent to any WooCommerce store checkout.
It can work in one of two modes:
- Site-wide: The Gidt Aid consent is always avialable at the checkout.
- Per-product: Specify which products need to be in the basket for the Gift Aid consent box to be show to the customer.
If you’re a developer, you can extend the plugin through its extensive use of WordPress hooks.
