"Break down the functions. Product catalog management, reputation management, sales process mediation, escrow, insurance, payment handling, and other stuff. These functions can be provided a la carte. What Amazon and eBay do is bundle it for our convenience, which admittedly is a value provided as well."
Amazon in fairness do add logistics into the mix, marketplace excluded, and we do all like the large discounts which that sort of scale affords.
