I toned down my Ft. Lauderdale/WPB gun show appearances, because it was the same dealers with the same stuff for the same price, and an unwillingness to barter, negotiate, horse trade, etc,...
A quick example, when the Ruger LCP first came out I went to a show with a co-worker CCW holder, cash in his pocket, hell bent on walking out with one.
First table NIB LCR: $349.00
Second table NIB $329.00
Third table NIB $299.00
Final table NIB, $279.00 and a free Nemesis holster.
The .380/AR-15 crunch that shot up prices in 09, into price gouging territory, has a remnant in "some" dealers....that bring the same guns back month after month.
The WWII/Korean/Milsurp dealers, are more flexible, to an extent, as I purchased a complete M1 Garand cleaning kit with every item, and knocked $15.00 off the priced when I mentioned Liberty Tree Collectors .com had them fro around $30.00.
Same with Garand Ammo belts, and bayonets. Dealers pushing Garand bayonets for $120 and up,....when the CMP lets you pick the brand, Oneida, AFH, Utica, etc,.. for one around $50.
Been yelled at by a couple of dealers, for mentioning Cheaper Than Dirt, has the same thing for less...(boy they didn't like that)...
But hey, I'll pay a fair price for something I want, but I research what I'm looking for, and if it's too high,......than look for another sucker to buy it. I won't..
