I do not mind how people post their sale stuff.
It is the attitudes that need to change. If someone sends a PM to a sale item you have respond to it. If you know you will be away for a few days don't put up the sale items, or at least put in your thread that you will not be able to responde for a few days.
There is also nothing wrong with just saying thanks for your offer, I have a few interested parties that I am negotiating with I will keep you in the loop.
