I meant to add Mexico as a good example of a category 2 Destination. In many places, postal service is very reliable and I have no problem sending to them. There are regions, however, where mailed packages tend not to arrive for whatever reasons. I am willing to ship to places like Mexico City if the buyer first contacts me with an address in a reliable area or area where 3rd-party insurance can be had for the package.

For now, I work with what we have. As I said, some regulars residing outside my ship-to nations use aggregators/drop shippers to package up their buys and re-ship to them outside the postal and FedEx/DHL methods reliably and at less cost. Delivery to some areas presently won't appear for some buyers. It would be nice to be able to accommodate them, but when I used to ship worldwide, they formed a tiny fraction of sales.
