Denon has been selling direct for years- then, there's the refurb dealer- why would anyone want to be a real Denon dealer when they have to compete with that, other than because of the convenience of local distribution or customers who don't shop outside of whomever they buy from without checking anywhere else? Regular customers are like Gold and anyone who works mainly with repeat business & referrals knows that.
The internet killed B&M, China has killed non-centralized ownership and once again, govenments that can't get along are killing economies. Trump's tactics are similar to killing ants with nuclear bombs.
