At the moment, discount codes can’t be restricted by payment method.
It would be very helpful if we could create a discount (or promo code) that only applies when the customer selects a specific payment method.
Example:
8% discount when paying by Bank Transfer
Extra 5% off when using GrabPay
On the checkout page, the discount could also be displayed on the payment method button (e.g. “Pay by Bank Transfer – 8% off”), so customers clearly see the benefit.
This would encourage customers to use preferred payment methods and improve flexibility for sellers.
