I had three books purchased by a buyer from Malaysia.
I sent him an invoice for USPS parcel post mailing. He refused to pay that, insisting that I use USPS International Flat Rate Mailing, which I did.
He subsequently filed a claim with PayPal which found in his favor for non-delivery. That was when I learned that USPS International Flat Rate Mailing can only be tracked to the point that the parcel left the USA.
After reviewing the horror stories I've seen posted here, I will file the $46 for merchandise, and the merchandise itself as the cost for education ... I now post very clearly on all items that I sell that I will not ship to Malaysia.
