Posta is a neighbourhood in central Kolkata, earlier known as Calcutta, in the Indian state of West Bengal. Once a citadel of Bengali mercantile aristocracy, it is now an extension of the whole sale market in neighbouring Burrabazar, dominated by Marwaris. The wholesale market features a wide range of products such as edible oil, salt, cereals, spices, food grains, sugar, and vanaspati products.
