If you don’t like the price or item being offered in for sale thread, take it to e-mail or PMs. Better still, just move on to a thread that is offering something you like the price on. If you post a criticism of the price or the quality of the item being offered, you will be in violation of Forum rules and subject to sanctions. If you post your own for sale items to the for sale thread started by someone else, you also are in violation of Forum rules. Start your own thread, rather than jumping into the thread of someone else. If your contribution to a for sale thread does not advance the sale, you are in the way.
