Are they one-stop in the US, though?
In Germany you usually have a little shopping center with Aldi and/or Lidl, a DM and an Edeka. Once you have finished shopping at Aldi and DM you can pop into Edeka and get the 1 or 2 items you didn’t get at Aldi and DM.
Many people in Germany are doing it like that. Edeka seems to florish from the people who prefer branded products and/or can’t get into 2 shops because they don’t go grocery shopping by car and can’t really visit more than 1 shop, because you can’t enter a 2nd one with a bag full of goods from the 1st one.
Oh, I go there too, occasionally. Especially for returning “Pfand” and buying wine, I really enjoy “Albali Reserva” (not Gran Reserva). It’s a more than decent Tinto for only 3.59€/bottle.
But somehow I never really grew fond of Kaufland. Somehow it’s always sort of filthy in there, shopping carts are often not to be found at the entrance, not enough registers are open, “chavs” are loitering at the entrance… I don’t know, I am always stressed out at Kaufland. Aldi, Lidl and Edeka feel more “cozy” to me, I guess.
