I've often wondered myself about the other poster's idea for a "stockless" gun-store where they order what you want as you want it, with a low flat markup. Perhaps even having internet terminals to allow people to browse for what they want, then compare the shipped, insured, and FFL'ed internet price to yours from your distributors.
As much as I like the concept, it just won't work. To be an operating business, the requirments for zoning for the business itself, and the ATF for the FFL to prove you're not a "kitchen table" hobbyist 01 FFL are tough.
The only way I could see doing it would be to take an existing store with inventory, take over the business, get the FFL, then "devolve" the business into the "internet store" mode over time, and perhaps they'll let you get away with it.
It would still be a struggle though, if people walked into an empty store without the warm fuzzies a ton o guns on the wall gives, they'll walk out again. You'd almost have to form a "buyer's club" and do tons of marketing to sell people on a store devoted primarily to the "order it" concept.
Also, there are two types of gun customers.
Type #1: They are the one time "deer season", "nightstand gun", "just got my ccw", or impulse buy guys who may not come back again for years, if ever. As long as the gun they want costs less or exactly what's burning a hole in thier wallet, they'll pay it.
Then there's type #2: People like us on the gun boards who collect, or have dozens of firearms and want more, or are continualy buying and selling new ones as thier wishes change. They also read and research obsessively.
And if customer type #1 is the majority of the business as I suspect, the one-gun impulse customer, it only makes economic sense to charge what they'll pay.
I only get "offended" when a store refuses to recognize me as type 2 customer, who knows of alternate sources like the few remaining kitchen table FFL's, on-line, and Shotgun News pricing etc.
So I don't get tweaked when I see price tags at or over MSRP, but when I politely tell the clerk who has a gun marked at $600, "Gun X is $400 wholesale, FFL X-fer is $50, and $25 for shipping, so how about $500 for a little more profit in it for you?" and I get a rude response, then I get angry.
So far, the "overpriced" but polite gun store in my area will play the "Wholesale +" game with me often enough, and still be polite when they won't, so I'm happy.
