Quoted from NM:

Debates on pricing on FS threads are generally fair game on a discussion group--most sellers realize this going in, otherwise they'd post a classified ad.
This is particularly here on Pinside, because the owner of this website's philosophy is:

His rules, his site.

Quoted from Sly_Old_Devil:

And then you say it isn't like a school drama you had 20 years ago? If you are in the clicky group then your FS thread will be all congrats and wish I was closer, if you are not in the cool group then it is more like open season, hopefully things average out across the price police patrolling schedule. Seems more like school than actual school IMHO. That is just life I'm afraid and I concur with the site owner and the majority here that basically keep it civil and in the classified section if you don't want an interactive thread, or become one of the cool kids. The agenda stuff has already been done to death as well so I'll leave it there.
As op says make an offer via pm, you never know unless you ask.
