title: Magento Promotions - Payment Method
body: <p>I would like to know if there is a plugin for applying discounts on the sub total when a certain bank credit card is being used for transaction. I am planning to connect different banks to my webstore. When a customer is purchasing a product, he/she can enter their valid credit card of the specified bank to check if they can use the discount on the sub total.</p>
  
  <p>There are any plugin or cart rule condition for that.</p>
