CST Brands is hoping to corner the market on convenience stores. The holding company, spun off from energy giant Valero in 2013, operates around 1,050 gas stations/convenience stores in the US under the Corner Store moniker. Its gasoline is sold under the Valero and Diamond Shamrock brands, while its stores are located in 10 US states and sell the usual -- snacks, drinks, tobacco products, health and beauty products, automotive products, and other convenience items. CST Brands has another 860 Dépanneur du Coin stores in eastern Canada (mostly in Quebec); however, the bulk of its Canadian stores are operated by independent dealers. In 2016 the company agreed to be acquired by Alimentation Couche-Tard.
