I've never actually been to the NY store, but I know a lot of photographers that I respect that love it, so when I said "one of the best stores in the world", I was basing it off that. I buy all my new gear from a local store, Norman Camera. I have never had better customer service at a retail store, and they have always been willing to match B&H prices.
Sometimes their prices on their website are lower, sometimes higher, but if you're price-shopping, it's a good place to look. Also, they have a solid return policy.
Honestly, the Best Buy sales approach bugs me. I had interviewed for a position in their photo department, but after learning their prescribed "tactics", I backed off.
I will respect a salesperson who wants to learn my needs and find a product to fit it, but when they try to fit their priciest products to my needs, I get bugged...especially after they make it clear they have no idea what they're talking about.
After all of that is said, I usually buy used anyway, since my hometown (Grand Rapids) has a pretty lively photo/video section on Craigslist...especially with Canon and Nikon gear.
