I visit the brick and mortar store fairly regularly. I am more than OK buying a major appliance there, and even a minor appliance. The camera department is small-ish, and the salespeople there are, well, OK, but not really the best trained for that one department. Not to say you can't find someone good, but overall, I'd shop somewhere else for photo equipment. B&H is my go-to, and second would be the refurbished route looking at the Canon Price Watch site, and one similar for Nikon.
I will say this for ABT... If you want an appliance shopping experience second to absolutely none, visit there, and make sure you have plenty of time on your hands to walk through full kitchen showrooms that will have you hear Robin Leach in the background talking his lifestyles of the rich and famous line from that show. Truly an amazing place. Think B&H physical store, but for home goods and appliances, and the like. Need a $10,000 outdoor grill? How about a 130-inch 8K flatscreen? Ever see every single color of Kitchenaid blenders all in a row? (There are a lot!)
What ABT really needs to do, if they seriously care about photo and video, is to move that department that is currently near the big fish tank on the main floor into one of their specialty store spaces in the circular indoor multi-story mall area in the back, like they did with their own version of an Apple store, and a dozen others. Yes, I did say mall. And it is.
