This town lost its only real hobby shop late in 2019,and all that's left is the Michael's store, which has little in the way of plastic kits. The next nearest real store is an hour away.
I was a fairly regular visitor to the real shop, perhaps 8-10 visits a year, sometimes many more, sometimes less. I talked to anyone and everyone while there (have to say, that is something that doesn't happen much at the bigger hobby shops, in my experience).
The shop owner became a friend, and he was very up-to-date on what sells, what piques interest and where the current trends were, in this town at least.
He carried a LOT of military, maybe because that was his own primary interest, and the shelves always seemed to be rotated as far as stock goes. I never asked how these guys felt about prices, but based on his shelves, it wasn't a big issue for him.
American cars sold ok for him, and he did tell me a few times that those buyers were pretty much all in my category - gearheads, car guys, and nostalgia buyers. Most of them were budget shoppers, in his opinion, and would go somewhere else to save a buck or two. I genuinely felt embarrassed when he told me this... I know a lot of those guys.
Import cars did ok for him, too, as did dedicated race cars like Rally, or F1, but he didn't stock a lot of those, due to stocking costs. He was quick to tell you that he could order in just about anything and those buyers seemed happy with that. A MUCH smaller group, those buyers. Price didn't seem to be much of an issue. A younger group than the domestic buyers.
He told me that most domestic car kit buyers stuck mainly to domestics, but a few like me at least would look at imports. Most of his import and race car buyers stuck to that genre only. Military buyers, he said, just walked past cars and trucks. They did spend time in his electric train section, but most didn't buy.
The trains sold VERY well, but to much smaller group, and they didn't seem to care anything about price. I'm thinking a much more affluent buyer, probably in the close-to-retirement age.
Sci-Fi and related sold well for him, but I never paid much attention to what he carried. That aisle always seemed to have someone in it whenever I visited.
He said many times that the Sci-Fi buyers usually started as young kids with their parents. Some were still coming back well into their adult lives.
His shop was off the beaten path, and that may have been a factor in most of the above.
At one time, I was seriously considering buying him out when he retired, and quizzed him on his business model, but it just seemed to hit-or-miss to me...
