In my town, when I moved here, we had about 3-4 camera stores... now, we have 1 store... the rest died off and no we have a monopoly. It's either that, if I want to try out a piece of gear, or go to best buy, which would be great if I wanted to get consumer lenses and bodies... and quite literally, to go to another store, I have to travel 2-3 hours... not going to happen. And because of that, they have no pressing need to stay competitive... Sales tax isn't a deal breaker... but it's factor in the price of goods... and frankly, most stores cant answer any questions I can look up online anyways... most employees being close to minimum wage and treating it as a job until they can get a better job. My last lens purchase, with their markup and taxes, it would have been about a $200 difference than adorama with free shipping. I'm not going to lose sleep for saving $200, especially when my bottom line is affected. Yes, I understand i'm on the honor system to randomly send usage tax to my state... they can bill me and I'll be glad to hash out the money with them...
