Yet another proof to the fact that cheaper doesn't mean better.
I'm no expert on euro prices, since the last time I was there the wall was still up. I've visited from time to time and even lived in Switzerland and later France but not long enough to make me european.
So I guess you are down to only two options...
Either wait for another Kurz to arrive or get your cash and find another dealer.
But as you said. TOmorrow is another day.
Anger tends to waer off overnight. Especially if you have a good drink and a nice pretty girl right next to ya!
