[2020] JUST LOST 30% coupon trying to make a buy

Each 30% discount coupon has usually 3 days term. However, if you starter a payment, applied your coupon, and then decided not to proceed with the payment the coupon will be temporarily locked 9 don't really remember for how long, I think it's only several hours). Anyways sending a ticket would be the best option. Even if your coupon expires by the time they get back to you, they can still track your payment attempts and they will help.
