Read the following case:

The idea of the eBay business model is simple and old. What residents of rural and urban communities have done for centuries is gather in plazas and markets to buy, sell, and exchange goods and services. eBay simply took this old idea and eliminated the need for a physical meeting between the buyer and the seller. The internet provides the cyberspace where the marketing exchange could take place. eBay simply created the software programs that enable transactions. eBay's system, however, improves on the old marketplace system in that the seller can "show" their products to a large number of potential customers at the same time. Considering that there may be more than one person interested in the item, the seller may hold a virtual auction, hoping that the demand for the item will produce a higher price than a typical market where the number of potential buyers would be more. limited or even non-existent. Obviously, the process also depends on modern transportation for the physical delivery of the product, since eBay does not play any role in the closing of the transaction. eBay charges sellers listing fees for listing an item, late fees for the value of a sale, and listing updating fees.
