In my little corner of Germany, the Nürnberg (Nuremberg) metro area, the Nürnberg city library (Stadtsbibliothek) charges about 10 EUR/year for a library card, and Volksbücherei Fürth is 18 EUR/yr for adults, with various discounts for students and public assistance recipients - the latter is a foundation.
But a card for the Erlangen-Nürnberg Universitätsbibliothek, and if you're willing to wait for delivery, every other academic library in Bavaria, was something on the order of 5 EUR, and required absolutely no connection with the university other than having an address in the area.
