It’s funny, here the Edeka (actually a co-op, not a franchise) would be the most expensive after the organic store (Landwege), it’s even more expensive than REWE (part franchise, part chain) which a lot of people cry about being expensive.
Coming from Ireland originally, now back here - I'd put Berlin Rewe on the level of Tesco (actually slightly lower, both in terms of quality and price) which is a mid range supermarket here. Edeka seems slightly lower quality / selection again.
The higher end large chain in Berlin would be Denn's and Bio Company. Which are both ludicrously expensive.
There didn't seem to be a mid-range fancy but affordable supermarket (like SuperValu or Dunnes Stores in Ireland).
Lübeck. Never been to the US, but our Rewes have a very wide range, which is a concept I like a lot, as for some products I'm fine with discounter quality, while I want more for others.
Actually really like Rewe! Was a complement comparing it to Tesco. Their sausage and cheese selections, and various unhealthy pre-cooked frozen treats are fantastic.
