Manners 101.
DO NOT BASH A POSTER OR HIS OFFER.
It's rude, and if others find the price acceptable for the item. Great. Both parties win. No one wants to hear that they are overpriced, or just bought crap.

NO COMMERCIAL
I will hunt you down and hurt you.. well, no.. But I really want to!

WHEN SOLD TELL US
That little triangle in the header on the right side will start a PM to the admins.

BE POLITE
Ok same as #1, but just because your momma may have spared the rod for you as I child doesn't mean I will..

REPORT VIOLATORS
That triangle thingy again.. We want to know about someone legitimately trying to rip off our friends, but remember not to cry wolf... Thanks.
