With the free version of the plugin, in the event that the cart contains products that cannot be purchased with the coupon inserted – Carta del Docente or 18app – the user will be notified with a message, directly on the checkout page.
With the premium version, on the other hand, you have an additional tool available, which allows you to display the payment method only if the products in the cart can actually be purchased with a Carta del Docente or 18app voucher.
