At Choffy, we work really hard to take care of you as our customer. In our new system, we are unable to add discount codes or coupon codes to your order after the order has been placed. We will however, allow you to use that unused discount code or coupon code on your next order, (so long as it has not expired.) That way if you forget to apply a coupon, like a first time coupon, it's not a problem! You can just use it on your next order!
