Free shipping means a slight increase in opening price. The shipping costs scare peeps off. If the price they see includes shipping, it’s like an incentive. I sold an original Parker Fly from 1996. Opening g bid 99 cents with free shipping. It sold ten days later for $1500. I paid $900 for it a few years earlier. Cheap stuff is a money loser on EBay. Higher ticket items fare better. It also helps to be brave.
