I encountered this problem: if I create a coupon that must be valid only once per user and this user has a problem with the payment and the order has a canceled amount (maybe because paypal had a problem) and he re-orders then the coupon is no longer valid because the system was used previously but in reality it is not true because the order is not "confirmed"
How can I solve it?
