On Payment Method discount rule plugin allows a nopCommerce store owner to configure discounts on the payment method which is configured in the discount rule.
The configured payment method is then matched with the payment method that which customer selects during the checkout process and if it matches then the discount rule is verified. This plugin won't work under two conditions, which is when coupon code is used it won't be applied directly as the payment method is not selected and the second guest users won't be able to avail of this discount.
Configure the plugin on the nopCommerce store:
1. The plugin works on the available discount types.
2. The discount requirement type should be configured as Must be assigned to payment methods.
3. Provide value for the Payment methods.
