Lessons to be learned about shipping USPS

I got contacted a month ago by a guy on here from Austria. He wanted to buy the complicated heat stove for a 72-73 Dart and I had a nice one advertised for $85. In Austria, evidently you can't register one of these cars unless they have 100% factory correct emissions equipment installed. I took it to UPS all packaged up and they gave me a shipping price of $325 - WOW (It only weighed 9 pounds packaged). I went down the street to Fed Ex and they wanted $368!!!. Needless to say I still have the heat stove and our friend in Austria is still looking.
