I'm pretty lucky in this regard. There's a small shop in town, but their stock-on-hand, like many small shops, has declined precipitously in recent years. Their main business of late is renting orchestral and band instrument to parents of school kids. (Our school district generally doesn't supply instruments.)
On the other hand, Alto Music's main showroom is about 15 minutes up the road, and they carry just about anything you might be hankering for. The place is HUGE! They have a walk in humidor just for acoustics guitars, with everything from Epiphone EJ series, to Martin D-45s, hanging on the walls. And, there's an employee who works inside the humidor who will be glad to help you with anything you want to try out. (Turns out I'm not a Martin guy....) I have also yet to find an uninformed floor person working there. They know the business, and the instruments they sell.
But, I also think that it's their online presence that makes the brick-and-mortar possible. And, they've opened 2 other locations. (Their original shop was in Dutchess county, and the Middletown store became necessary because they were getting too big! The original location also remains open.) Don't get me wrong, they do a brisk business, and there are always other people in the store when I go there. (And because my days off rotate, a lot of times I go are not exactly "prime time".) But, that's a lot of real estate to finance...
