My take on "lowballers" is this. If I offer up a heli for let's say $500.00, I expect to get it sold for between $400 and $450. Now sometimes you have to take less if you really want to sell it, but usually that's the spread. Now if someone offers me $50.00, I'm just not even going to respond to them because they are obviously a moron.
But if a guy offers me $300, I'll tell him he has to come up to a more realistic number or I'll give him a counter and see where it goes. It's a game and if you aren't ready or willing to haggle a little then you don't get the rules of the game.
Now someone who posts "FIRM" is limiting themselves on their ability to sell the item. If you say $850.00 FIRM, why not say $975 "negotiable"? You'll probably get more bites and you may even get your price or more. So the buyers job is to get it for the least amount of money and the seller tries to get the most. Nothing to get upset about.
