Yes, you can. There are two types of order cancellation:

1. Canceling a paid order.  If you haven't received the shipping notification, you can cancel this order under "My Orders". Or you can contact our customer service by Chat or Ticket.

2. Canceling an unpaid order: An unpaid order will be canceled automatically after 24 hours. Or please log into your account >> click on "My Orders" and click on the "Cancel Order" button. Your order will be canceled. Please find an example picture below. Please note that we CANNOT cancel orders which have been shipped out. 

Therefore, please wait for your package to arrive and you may either keep it or contact us to return for a refund. Please DO NOT refuse the delivery as the undelivered package will be destroyed by the third-party logistics.
