Can you please add the “Disallowed Customers” option too? There is already the option of Allowed Customers, but we need the opposite. There is also Disallowed User Roles, but we want to make sure certain customers cannot use the coupon.
Our use case:
– due to technical issues, customer did not receive an email with the coupon code in it
– in spite of this, she made a purchase
– later complained that she had not received the advertised discount
– so we did a partial refund to please her
– now we would like to make sure she cannot apply the coupon in question to her next order
Could you please put this feature request on your roadmap?
