I checked with my local dealer today, they could not even find the MK III in their system. That's strange, since they sell a lot of cameras at their two local stores as well as operating a big online store (onecall.com)
I was in Seattle last week and stopped at Fry's to see if they had the MK III. What a disaster. They had only two Canon DSLR's, which were two 70 D kits, one Nikon DSLR Model, and a Sony or two. The other 90% of their display was empty. Same for P&S cameras, no high end ones and lots of empty spaces.
I'd say that they are in big financial trouble from the look of things.

Washington State requires that I pay sales tax, and my accountant makes sure it happens. Just because B&H does not offer the convenience of handling tax for me, does not mean that its due.
Sounds like you doing it for living
My Cameras are owned and purchased by my business for product photography. They may also get used a little for other uses, usually charity work.
However, even if it wasn't a business, I still owe taxes.
As an US citizen, I feel we already paid enough taxes. I might be the odd one here, but I didn't feel guilty for not paying sale tax on my 1dx at all.
