Yes, you can. There are two types of order cancellation:
1) Cancelling a paid order: If you haven't received the shipping notification email, you can contact us to cancel the order.
2) Cancelling an unpaid order: An unpaid order will be canceled automatically after 5 days.
Please note that we CANNOT cancel orders which have been shipped out. Therefore, please wait for your package to arrive. You may either keep it or return it for refund. Please DO NOT refuse the delivery as the undelivered package may be destroyed by the third-party logistics.
