The main key to being safe when shipping internationally is getting confirmation or a tracking number to prove that you have shipped the item. If a person files an unrecieved item claim through paypal and you have no confirmation, then you have no way to defend yourself. It is the most important thing above all else. Talk to a postal store employee to ask them about information regarding confirmation of international items. They should be able to tell you what services are offered that allow you to track the item. Once you have a proven method, then stick to it. And don't forget, gettting the cheapest option is not always best for you.
