full_context: Document 1: AH Basic: AH Basic is a discount brand of everyday commodities developed, marketed and introduced by the Ahold group, to replace the Euro Shopper discount brand in all Albert Heijn stores in Belgium, Germany and the Netherlands from April 2013 to 2014.
Document 2: Discount store: A discount store is a retail store which sells products at prices that are lower than the typical market value. A "full-line discount store" or "mass merchandiser" may offer a wide assortment of goods with a focus on price rather than service, display, or wide choice - such as Aldi and Lidl; a "speciality", "single line", or "category killer" discount store may specialize in specific merchandise such as jewelry, electronic equipment, or electrical appliances, relying on bulk purchase and efficient distribution to keep down cost - such as Toys "R" Us and Staples. Discount stores are not variety stores, which sell goods at a single price-point or multiples thereof (£1, $2, etc.). Discount stores differ from variety stores in that they sell many name-brand products, and because of the wide price range of the items offered. Following World War II, a number of retail establishments in the U.S. began to pursue a high-volume, low-profit-margin strategy designed to attract price-conscious consumers. This strategy has received renewed interest from retailers and customers alike stemming from the Great Recession that began in 2007 that forced buyers to revisit the approach to the products they wanted.

Document 10: Store brand: 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.
