All the Scando countries are expensive but the further north you go, the more expensive.
So all the Danes take trips to Germany, all the Swedes take trips to Denmark and all the Norwegians take trips to Sweden to get cheapER beer.
And the ferries between Denmark/Germany have tax free shopping on board so people go for a ferry ride with a trolly and load up with a few tax free slabs.
Crazy Scandos!
