i figure on internet sales it's to cut down on tire kickers wasting their time.
but it's rare for me to see a gun sold by any venue that does not have a real price on it that i'll even ask about it. from when i used to get a table at shows w/ my dad, i saw dealers give 5 different prices to 5 different people. all i can figure is they've got a bottom line they really want for the gun and size up the individual to figure out how much above that amount they can get out of him.
i had a dealer at tulsa once hem and haw for 2 minutes to give me a price on a colt new frontier. i finally said "look, i drove 5 hours to get here. the shows been open a day and a half. if you've not figured out by now what you want for it i'm moving on." he didn't and i did.
if you're a legitimate dealer and the gun's for sale....PUT A PRICE ON IT!
