Here is a Blurb from the BST section of the rules posted on this board. No one reads them but they are still there

-
Once any transaction is completed in the Buy/Sell/Trade areas, or over with, that transaction shouldn’t be deleted. Specific pricing, or confidential information may be removed but the other information should stay.
My motto over there has always been the fewer rules the better. Don't scam anyone, communicate a lot and act professionally. All will be good if that is done. Knock on wood but the BST is one of the smoothest parts of the site as far as moderating goes. As far as leaving pricing after a deal is done, I usually will remove it as a courtesy to the buyer.
