Do those advantages continue to scale last a certain point? I use a service called Fresh Direct for groceries. They serve nearly the entire NY metro area, so they’re pretty big, but not nearly as big as a national chain. The quality provided by Fresh Direct is so much better than Whole Foods or Shop Right. The reason is that they partner will smaller producers that sell really good stuff. Like they have really good yogurt from Brooklyn, amazing organic produce from a cooperative in Pennsylvania, pasture raised meat, etc. Whole Foods used to have similar items before they were purchased by Amazon. At least for my personal shopping habits, bigger doesn’t necessarily mean better.
