alt Hacker NewsAldi seems to. I thought of them as I read about Costco, not because of the size of their stores (which are generally quite small as supermarkets go) but because of the limited choices. Aldi normally has everything I need but doesn't have a lot of choice in any individual thing. It makes shopping there feel very efficient.
Walmart does this too, and it's one of the worst experiences/value-propositions I've ever experienced. It might be better in the US but in Canada it's expensive, poor quality and painful: pick three.
