There are no Trader Joe's stores in Germany. It was bought in 1979 by the German family that owns the Aldi Nord chain of discount stores[0]. That German chain uses the Trader Joe's brand for some American-themed fast food ingredients, nuts, and sweet ice tea.
[0]: Which is different from the Aldi Süd chain of discount stores which runs stores under the "Aldi" brand in the US.
I'm sitting in Toronto, and am in the process of getting my Canadian citizenship. One of the things I was looking forward to was getting a Canadian passport and having easier jaunts in to upstate New York for Trader Joe's runs.
I can't believe they opened stores in Germany, but never bothered to open one in Vancouver, where there was proven demand for their products.
