The surplus business is the buying and selling of goods for recycling, remarketing or repurposing. By definition, surplus refers to goods which are no longer needed by their owners. Practitioners of the surplus business distinguish themselves from salvors, who deal in salvage goods, which are damaged and available as a result of an insurance claim, fire, flood, etc. Surplus goods range from "new and perfect" (eg "last year's model" of automobile, camera, etc.) to well-worn machinery or obsolete computer chips, whose only value is the gold or other metals they contain. Typically, surplus goods are sold "as is - where is." eBay, for example, began as an electronic yard sale for unwanted wedding gifts, garden tools, etc. It has since become a worldwide phenomenon. A dealer in surplus may refer to another informally as a a fellow surpie.
