Here's something interesting: a flea market event where online-based sellers of, I guess, both traditional and non-traditional flea market merchandise will be at a physical flea market showing their merchandise and, obviously, plugging their e-commerce sites, too.
I do suspect that laptops are going to start become more common on-site/on-location as tools for flea market dealers and flea marketeers (management), especially if there are electrical outlets nearby! :)
