Price policing has become a blood-sport here on pinside. I would suggest that for every deal you see here, there are far more occurring outside the forum listings.... and that number is likely growing.
Its great exposure, but sellers will have not just their game and price examined but even their motivation for selling will be scrutinized....
Obviously its a private site, and the owners can do as they please, BUT:
Of ALL the forums I participate on, across a variety of hobbies and interests, NONE would allow the kind of bashing that is common here in for-sale threads....
I know that kind of change would ruin the fun for the price nazis, so that's certainly a concern if they were ever to tone down the bashing....
