From what I can tell, they used to have a very basic web page with just their name and address and a list of what they carried - I remember seeing it and being frustrated by it years ago, as they're one of just a handful of shops that carry certain high end brands. Other places have inventory and photos on-line, which is a much, much better way of doing business. It means people are more likely to stop in, as they know more or less what you have in stock, *plus* people will actually order hard-to-get instruments no matter how far away they are. My guitar came from a smallish shop in Tennessee - I knew more or less what model I wanted, the shop had a good reputation, I was able to talk to them about it over the phone and even hear it that way (some can even do MP3s), which isn't as good as hands-on...but for rural folks, it may be the best they can do.
Now...some places don't want to deal outside the local area, and I can understand that. But you also increase just local traffic if people know what you've got. And we've got a HUGH rural state above us, plus a lot of land around us. People come from a long way away to shop in Fort Collins. A website could well be a draw for many. Ya never know.
They don't even have the basic website anymore. Dunno what happened. There are references to it in some places on-line, so I know I'm not imagining things!
There was a comic book store here in Austin some time ago, the owner of which we had occasion to speak with about his very basic website. Turned out he was purchasing the service from a provider who was charging him $1000/month for the (not very good) website. If something like that was going on with the guitar store, then perhaps they would be surprised to learn how inexpensively a website can be done, nowadays.
