Quite a few years ago, we had a specialty retailer in NJ that consistently beat everyone else’s prices on TVs and kitchen/laundry appliances. They were in business for over 50 years, and their sales volume was huge.
A couple of years after the founder died, his kids expanded to a couple more locations, and a few years after that, they sold-out to a Japanese conglomerate. The conglomerate apparently didn’t know how to run that type of business, and the whole operation went belly-up in a few years.
