HI Christine Thank you for your reply.Our main problem is that due to the price on our system is USD1.88, we can only use FedEx for shipment according to this price. Our accountant is warning us of this problem,We have informed our accountants of the way you suggest, but they still do not allow us to do so.Could you help us to try if there are other possibilities ? We apologize for the inconvenience we have caused you.
