C&S Wholesale Grocers is at the bottom of the food chain -- and likes it that way. The company is New England's largest food wholesaler and second in the US (behind SUPERVALU), delivering groceries to some 4,000 independent supermarkets, major supermarket chains (including Safeway), mass marketers, and wholesale clubs from Maine to Maryland. The company distributes more than 53,000 items, including groceries, produce, and nonfood items. C&S also sells groceries through Grand Union supermarkets.
