All but one of the Cox Family Stores are located in the Tri-Valley area of Northern California. As of 2015, the chain maintains a total of nine locations: four in Dublin, two in Pleasanton and one each in San Ramon, Tahoe City and Truckee.
Cox Family Stores opened its first convenience store in Dublin, California, in 1976. Three generations work in this family business headquartered in Pleasanton, California. Besides the usual convenience store items, Cox Family Stores sell Shell or Chevron fuel, Caramel Valley Roasting Company coffee and offer car washes. Because the family believes a bathroom is an indicator of how the business regards its customers, Cox Family Stores have "amazing" bathrooms with tiled floors and walls.
