I was really hoping, perhaps foolishly, to hear from dealers with an explanation of their pricing policies.
Dealers at gun shows will have different strategies and circumstances than brick-and-mortar dealers, mostly because gun show dealers won't be there to support the product or to take the heat for questionable pricing.
That's not to throw all, or even most, of those folks under the bus. Free market and all. Still, a guy with a fixed storefront has to think (and act) in the long term, and his reputation matters to him.
Joe Bob selling Glock mags for $70 before THE BAN is just out to make a quick buck, and he doesn't have to worry such things.
