Grey Market

What is Grey or Gray Market?
•A grey market is a market where a product is bought and sold outside of the manufacturers authorized trading channels.
•Grey market is an unofficial market in which goods are bought and sold at prices lower than the official price set by a regulatory agency
•A grey market or gray market is the trade of a commodity through distribution channels which, while legal, are unofficial, unauthorized, or unintended by the original manufacturer. In contrast, a black market is the trade of goods and services that are illegal in themselves and/or distributed through illegal channels, such as the selling of stolen goods, certain drugs or unregistered handguns.

Description of Grey Market
Unlike black market goods, grey-market goods are not usually illegal. Instead, they are sold outside normal distribution channels by companies which may have no relationship with the producer of the goods. Frequently this form of parallel import occurs when the price of an item is significantly higher in one country than another. This situation commonly occurs with electronic equipment such as cameras. Entrepreneurs buy the product where it is available cheaply, often at retail but sometimes at wholesale, and import it legally to the target market. They then sell it at a price high enough to provide a profit but under the normal market price. International efforts to promote free trade, including reduced tariffs and harmonized national standards, facilitate this form of arbitrage whenever manufacturers attempt to preserve highly disparate pricing. Because of the nature of grey markets, it is difficult or impossible to track the precise numbers of grey-market sales. Grey-market goods are often new, but some grey market goods are used goods. A market in used goods is sometimes nicknamed a Green Market.
Importing certain legally restricted items such as prescription drugs or firearms would be categorized as black market, as would smuggling the goods into the target country to avoid import duties. A related concept is bootlegging, the smuggling or transport of highly regulated goods, especially alcoholic beverages. The term "bootlegging" is also often applied to the production or distribution of counterfeit or otherwise infringing goods. Grey markets can sometimes develop for select video game consoles and titles whose demand temporarily outstrips supply and the local shops run out of stock, this happens especially during the holiday season. Other popular items, such as dolls can also be affected. In such situations the grey market price may be considerably higher than the manufacturer's suggested retail price. Online auction sites such as eBay have contributed to the emergence of the video game grey market
