Hi, I think every long ebayer has had this problem. I recently got the raw end of a deal on a $55.00 sale to Indonesia. They specifically asked for the cheapest cost to post it there, then 2 weeks later opened a item not received dispute on Paypal, I tried to explain to paypal that they asked for the cheapest post method, when I supplied my Australia Post account details showing the customs label number and the Australia Post invoice, they still weren't satisfied. Result - buyer gets their item, I loose $55.00. A rip off, too right! 

As a result I no longer offer international post. And along with the increase listing and store fees I am slowly closing down my store after 9 years of trading.
