I have shipped stuff all over the world, every once in awhile something will happen. I only use USPS, but you lose all tracking when it gets the country you are sending it to. You have to trust the buyer and their postal system, some are as crooked as a dogs hind leg. Of all the ones I have sent I can remember a few that never made it to the buyer, I just send another, and with one exception they all made it the second time. On the one that didn't, we were pretty sure it was his post office where it was disappearing so we worked around that office and sent it to his brother, it was "third time was charm". I had dealt with him several times before, so I trusted him.
There are some buyers that can be scams, it is up to you to find them on your own, gut feelings are about all that you can rely on. A few emails are all you will have to make that determination. You will be out postage, time and supplies, not a great amount of money, more of a disgusting feeling that someone took advantage of you will hurt more than the money loss. The other option is no international orders.
