My first surprise on arriving at the store was to see the word "EXTRA" featured on the signage outside instead of "METRO." I soon learned that the Future Store operates under METRO's "Extra" banner. Apparently, the average German is not familiar with the "METRO" name since its stores operate under a variety of different names. Aside from the words "future store" in small letters on the sign, from the outside this store looks like any other supermarket.
