Where to buy Schonenberger 70% Cacao chocolates in/near Zurich?

Question is in the title :-): Schonenberger 70% is delicious, delicious chocolate - but I've only had it when my friend from Schaffhausen brings it. Where can I find it in/near Zurich? Preferably in a large quantity, I'd like to bring some to my friends in the U.S. :-)
