it's still a lowball lol, just because you think you know the market value better than the seller doesn't change that, whether you do know better or not is not relevant. the fact is market value is what someone is willing to pay for something, if he keeps the ad up long enough, eventually a sucker will bite.
So, If I was asking $1,275 in today's market for a used franken-AR built with PSA PTAC parts, and someone offered me $450 (pretty close to actual investment on the new parts
with shipping), you would consider that a "low ball" offer? Because that's the kind of insane asking prices some of us are seeing.
Just to be clear, I'm not crying foul about people asking for ridiculous amounts of money for their used junk. That's their business, and if they don't need the money and can sit on it until your "sucker" comes along (if ever), good for them. But I
do have a problem with these people getting huffy when they receive a reasonable offer, and I also have a problem with calling fair offers "low ball" just because the
asking price is astronomical in a given market. A true low ball offer is (as you'd see from multiple sources in the link) one which is absurdly below market value, to the point of insulting, and, especially if the seller is in a tight spot, aiming to take advantage of them. A true low ball is as deserving of an eye roll as these stupid high asking prices, and I've certainly had my fair share when selling things, like a guy who wanted my freshly rebuilt Losi 1/8 scale nitro monster truck for $120 ("it's all I got!"). That was about half of market value for one with an original, tired .26 sport engine, where mine had a brand new body and a nearly new .32 engine. Fair value was closer to $300, and I wound up taking $270 a few days later.
We can agree to disagree, but if you don't understand the difference between low balling and making a reasonable offer on an item listed with an astronomical asking price, I'd say you're part of the problem with the bloated figures in today's classifieds and consignment racks.
