A coal-dealer is someone who sells coal, but there are several other terms that are synonymous with this profession. One such word is coal merchant, which is often used interchangeably with coal-dealer to describe someone who specializes in the sale of coal. Another similar term is coal trader, which may refer to someone who buys and sells coal on a larger scale. A coal supplier is also someone who provides coal to customers, but they may not necessarily have a physical storefront for direct sales. Finally, a coal distributor is someone who transports coal from the supplier or dealer to the customer, often in bulk quantities.
