Two family owned grocery chains spent decades competing against each other in the Twin Cities.
Both upscale. Both well regarded. Both serving essentially the same customer in overlapping neighborhoods.
Then they merged.
The obvious move after a merger is to pick one name. Consolidating to a single brand saves money on signage, advertising, packaging and every printed thing, and it simplifies everything about running the company.
They did not do that.
They kept both names, and still run stores under each.
That looks like sentimentality or indecision. It is neither, and the reasoning behind it is one of the more useful lessons about what a brand is actually worth.
