Two months in Marburg - and no Taxfree

Over the last couple of months, Mr Columbus and his navigator Mr GPS has told me I was in the Marburg area in Germany.  They told me they could see some satelites swirling around, but I was not allowed to get myself a fix. (!)

Well, today I took my Yeti home.  All I had to do was to give 2.600 NOK in exchange of a new shark fin. 

At least Mr Columbus is still speaking english, even after 2 months in Germany.

But where is my taxfree?
