Wikipedia
Store brands are a line of products strategically branded by a retailer within a single brand identity. They bear a similarity to the concept of house brands, private label brands (PLBs) in the United States, own brands in the UK, and home brands in Australia and generic brands. They are distinct in that a store brand is managed solely by the retailer for sale in only a specific chain of store. The retailer will design the manufacturing, packaging and marketing of the goods in order to build on the relationship between the products and the store's customer base. Store-brand goods are generally cheaper than national-brand goods, because the retailer can optimize the production to suit consumer demand and reduce advertising costs. Goods sold under a store brand are subject to the same regulatory oversight as goods sold under a national brand. Consumer demand for store brands might be related to individual characteristics such as demographics and socioeconomic variables.
