And how does the poor buyer that is walking 700 meters know that? So he wastes time again because you do not want to sell at that time. I have a good idea, if the items is locked and a player shows up it disappears!!!
Not serious but there is no point in showing something I cannot buy right at the moment. if you want to eliminate the frustration for buyers then don’t show it. Why does the buyer have to pay for a choice the seller is making? Of course we do not even know if it is possible to not show it until someone tests it.
