alexyomar,
i have been using USPS services few time (on Ebay).
in malaysia we have Post Malaysia(PM) but the service not as excellent as USPS.
lost the item during transit using USPS to Malaysia....
according to the procedure (PM). any registered mail/item/shipment from USA.
they will change to local code... in order to know/update the code we have to call KLIA/Sepang service center to get an info...
it would be best to use FedEx to ship any item from Malaysia to USA/ USA to Malaysia
to avoid any problem during transit & easy to track for both parties.
the cost slightly higher then normal but its secure the item... hassle free...
i've been inform DHL no longer operated in USA... by few seller.
UPS very expensive...
