I once sold a rare 19th century collectible on FB Marketplace. $500, but it was worth much, much more. I specifically chose the option to sell locally, either pick up or meet up. In the Indianapolis metro area, this was perfectly feasible. And it did sell locally after a couple of weeks to a nice guy who chose to pick up from my home. But I got countless people messaging me, wanting it for $50 or less AND wanting me to ship it to them across the country on my dime. Absolute clowns.
