The problem is no given retailer has the sort of market power Amazon does. There are at least a dozen grocery reatailers in my smallish city, and dozens nationwide. In fact, merging grocery store chains are frequently forced to divest of stores in order to ensure communities have multiple options.
There are some who came close, though Amazon is in a league of its own. Sears Roebuck, in its day, aalong with Montgomery Wards (which long had a bad reputation with both sellers and customers), K-Mart, Walmart, and before them the railroads and AT&T.
There are a few grocery chains with national reach (and they've been further consolidating), but none controls major markets (rural regions are often another story).
