This is what I do because I hate negotiating and completely ignore those that like to do it. If someone has an item I want and it is more than I will pay I will make my absolute best offer. If the seller does not accept it I move on and feel no need to communicate anymore.
As far as quoting recent sales it is the best way to get me to ignore that person no matter if I am the seller or buyer. We all do stuff different and I am not saying my way is perfect, it is just how I do it.
