Since PayPal sends back all the details only After Payment, therefore if member did not login before checkout. Registered Airmail will be selected as shipping method and flat rate shipping fee will apply. After we received order information, we will calculate the corresponding shipping fee and refund any differences by cash coupon.
In addition, since orders with more than one items cannot be consolidated and need to be sent by registered airmail, shipping fee will be calcauted separately and registeration fee apply on each shipment. Therefore the overall shipping fee is generally higher compare to consolidated shipment which charge by total weight with only one registration fee.
