Is there an app or way to limit one card only to be used with a discount code or order.
Same people keep changing their names with adding a free mystery gift.
Topic summary
Main issue: A merchant seeks an app or method to restrict discount redemption/order placement to a single credit card, aiming to block repeat claims of a free “mystery gift.” Customers are reportedly changing names at checkout to bypass current limits.
Goal: Tie eligibility to the payment method (one card per order or per discount) rather than customer name to prevent promotion abuse during checkout.
Status: No answers or solutions are provided; the request is open. The merchant is specifically looking for recommendations on apps, platform settings, or checkout controls that can enforce card-based limits on discount use.
