A large percentage of the over inflated prices are due to stupidity and greed. Most people that have a single piece of ordnance obtain it in a collection of things they received as a lot, and know nothing about ordnance. They go to a gun show or flea market and see a similar shaped item that is indeed rare and has a high price. So, being completely ignorant of what they have, they price their common scrap at the same price as the rare piece.
If enough people pass by, eventually there will be some idiot that wants the item, and knowing nothing of what it is really worth, pays the inflated price. They take it home, study it, and discover they could have purchased 20 of the same item for what they paid. They get butt hurt that they were screwed because of their ignorance, and decide to resell the piece at what they paid for it.
In the mean time, the original seller is encouraged to continue overpricing things because it worked for him. He might even get into the ordnance business because he has been encouraged to overprice items and screw people. If the guy who bought it from him is able to resell it at the inflated price, then he is also now encouraged to obtain cheap ordnance and overprice it.
It is a vicious cancerous plague that is spreading. I'm thinking we could cure this, if we were allowed to bitch-slap anyone that we see selling ordnance at these ridiculous prices. Eventually after being bitch-slapped enough, they would get the message and lower their prices.
Just a thought.
Another variation is the person that joins BOCN so that he can get us to put a price on his ordnance that he knows nothing about, and then resells it on ebay or Gunbroker, and we never hear from him again. Bring anyone to mind?
