Corner groceries in Europe have a surprisingly large variety. You may not be able to get everything you get at Costco, but you&#x27;d be surprised how much you can get, a little bit at a time.<p>I spent a few months living in Berlin and routinely shopped at places like Kaiser&#x27;s and Netto. I never had any problems with product selection or diversity.<p>But yes, there are other differences in consumption patterns and psychology, too. As a general statement, everything in W. Europe is more minimalistic, since there isn&#x27;t so much room to just store &quot;stuff&quot;. It&#x27;s hard to describe exactly what you would buy instead or what you&#x27;d do differently without knowing you closely, but I think you&#x27;d find it&#x27;s a completely survivable adaptation. :-)
