Grocery shopping is on almost everyone’s weekly list. For many households, that means driving to the supermarket, or an even larger discount mega-store, and loading our carts to the brim with our favorite brands. But grocery shopping wasn’t always this way. A century ago, small mom-and-pop grocers dotted street corners, staffed by storekeepers who packaged bulk items for customers they knew by name. Today, the retail landscape continues to change, as more of us go online for a variety of purchases.
