If you'd like to change your shipping address, you can do it in your end before the shipment including unpaid orders.
First, please log in your "My Orders" program and then click "View detail", find "edit" button below your shipping address and then change in your end.
To ensure that your package can be properly delivered, please ensure that your address is complete and correct with all information including apartment/suite/room numbers.
Once your package shipped, we will not be able to change the shipping address. And we are unable to cancel an order after shipment. Please keep an eye on your order status by checking "My Orders" to make sure you can receive your order.
