It’s easy to ridicule the have-nots when you’re a have.
I wouldn't say have nots, but would say "don't know's"
Were I brandy-new, and had to have something absolutely, positively tomorrow no matter the cost, then yea, I'd probably take whatever was listed at face value.
I think everyones been in that position at one point or another.
A lot of it may come from a lack of understanding on the buyers part, and that can apply to anything, not just glocks, so I'm not singling that out by any means.
Could be the "Well its not on the list so if I have to pay X amount so be it" mindset.
Could be that "Its listed for for way more and has Pre-Ban in the title so I'm comfortable with paying that much more"
Could be that all the info the buyer recieved is from either facebook or "My friend at the range said....."
Or their value of Object X is based off the going rate on armslist/ gunbroker/ wts ads.
Could be people get caught up in rush of paying 75% over retail or m.s.r.p.
