To the buyer....an item is worth what he is willing to pay.
To the seller...an item is worth what he can get for it.
This is the bottom line to any deal.
I worked in an old fashion type gun shop back in the late '60's, early '70's. We did a lot of horse tradin' in those days.
We used to say that if both parties were happy with the deal, it was a good deal. Many came back, some didn't. That's life.
I've recently sold a few handguns on the Internet and I've purchased a couple also. So far, so good. I'm actually ahead right now.
What I've found lately is that there are a lot of "tire kickers" out there with no jingle in their pockets to buy the right time of day. They are usually the ones who do nothing but complain about the prices being asked.
I presently have a 1st generation G17 (pebble grain frame) for sale with two NFML mags and Mepro night sights in the original box and in real good shape for a 13 years old pistol. Five people have inquired and only one seems to have the $$ to be a serious player. A couple of the others seem to think I should give the pistol away because they don't have the $$ to spend. Looking is cheap, buying takes money!
One has to read the whole deal before they come to a decision on a fair price. Many semi-autos come with night sights or pre ban standard capacity magazine. Both options can raise the price of a standard pistol substantially.
The guys that really piss me off are the ones who come back at you with, "Ill give you..." or "I can buy the same gun for..."
You'll give me nothing because I won't even respond to you. Go buy the same gun where you say you can. They never seem to buy that one, do they?
The pending deal could/would go much smoother if they would use, "would you consider"?
For the most part, many of us can not walk into a gun shop/firearms dealer and find the "inventory" that is listed on the various sites on the Internet. If you don't like the price, pass it by.
