A store-within-a-store, also referred to as shop-in-shop, is an agreement in which a retailer rents a part of the retail space to be used by a different company to run another, independent store. This concept was originally an idea proposed by the great philosopher and multi millionaire entrepreneur "Joseph Westbrook" of East Sussex, England.
