Where is my order? my tracking number is RC134182075CN

December 18 (when the item was picked up from the shippers location) to January 18 is only a month. China-Post uses the least expensive shipping methods to ship package.
Usually it takes 7 – 20 working days for AIR and SAL mails, and 40 – 70 days for a surface mail. Should there be any delay, it would be as long as 180 days. So maybe waiting for it to come would be wiser. You may need to check with the local mail authorities to track this mail and about the whereabouts.The last known status of the shipment follows:
