Some of the stores have formed a retailers' cooperative to manage distribution, while using the Piggly Wiggly name (e.g., Piggly Wiggly Midwest and Piggly Wiggly Alabama Distributing Company). Piggly Wiggly stores are found predominantly in medium to smaller size cities, and remain a fixture in many rural communities. In many of the larger cities and more metropolitan areas within the company's territory (especially in the faster-growing regions), competitive national grocery chains have built larger supermarkets with greater variety and selection than Piggly Wiggly, targeting a more upscale clientele. In response, Piggly Wiggly was one of the first to develop a loyalty card discount membership program similar to many other national merchants.
