Consumers have more choices than ever on where to shop for groceries and a new report from Planet Retail indicates that they're making their choices based primarily on convenience. "Everyone covets convenience -- shoppers and retailers, "says Planet Retail US research director Sandy Skrovan. "Busy lifestyles -- two working parents, hectic homes and job schedules, lengthy commute times -- are driving up demand. Modern meal preparation and eating habits speak to a move toward on-the-run, grab-and-go consumption."
