I used to do exactly as Pete but have recently been using the Ebay Global Shipping Program, Easy enough with no problems (so far). I've sold 11 items this year to Hong Kong, France, Italy, Germany & Belgium I'm not actually sure what would happen if there was an issue with the item and a return was asked for, as although I stipulate "No returns" Ebay ignore that and freeze your PP payment, ( I know they're meant to be seperate but the payment was frozen 2 hours before the email from ebay).
Maybe the OP could ask the trader in Germany to list an item in that way?
