Probably half to two-thirds of my grocery shopping happens at Target. Almost all the rest is WinCo or Stater Bros, or occasionally 99c Only. There are other chains in the area (Vons, Albertson's, Food4Less, Ralphs, a couple of different "ranch market" stores, Walmart), but the experience, selection, and pricing is not as great, so those places are "last resort" destinations. (The experience at 99c Only is not great, but they've got winning pricing.)
