11. Why do you charge my card more than your product price?We only receive your order price. As we are from different country use the different currencies, So the extra money may be charged by the bank as the bank fee. It is a fee for overseas transaction, for the currency exchange rate fee. Hope you can understand. If you still have problem, please email to us.
Never mind the chingrish of their answer. This is straight up BS.
