How do I Enable or Disable WooCommerce Coupons by User Role?
The light-weight Role-based Coupons plugin extends the functionality of WooCommerce Coupons by enabling or disabling the use of coupon codes based on user roles. For example, if you only want Administrators and Shop Managers to be able to use coupons, you can select both of these roles to enable the coupons. By default, the use of coupons is disabled until a user role is checked. This plugin presents all available user roles, even if they are custom user roles. You can enable as many or as little user roles as you would like.
