Some people canceled their orders after confirming it.
Because the international shipping charge is higher than they thought.
If it is possible that you cancel your order depends on the international shipping charge, please ask me before you add the items to the cart!
Once you add the items to the cart and send order, other people can't buy them.
This is extremely troubling to the other customers.
If you cancel your order after confirming it, you can't use my service.
