When it comes to grocery chains, Trader Joe's isn't your average Joe. With more about 460 stores in nearly 40 states, the company offers upscale grocery fare such as health foods, organic produce, and nutritional supplements. To keep costs down, its stores have no service departments and average about 12,000-15,000 sq. ft. Trader Joe's stocks about 4,000 items, 80% of which are its own private labels, including its signature Charles Shaw brand wine that sells for $3 a bottle, soup, snacks, and frozen items. Started by Joe Coulombe as a Los Angeles convenience store chain in 1958, fast-growing Trader Joe's is owned by German billionaire Karl Albrecht, who founded the ALDI food chain with his late brother Theo.
