FOOD LION
Here is a new one we learned about this week. Food Lion operates approximately 1,300 supermarkets in 11 Mid-Atlantic and South Atlantic states as well as Tennessee, Kentucky and West Virginia under the Food Lion, Harveys Supermarket, Bloom, Bottom Dollar Food, and Reid's banners. It may sound familiar to some in the midwest and midsouth, as they expanded greatly in 1990s, but declining sales forced them to retreat back to the East Coast.
Obviously this box can be found at Food Lion stores, and possibly their other associated chains listed above. Thanks to SWFan for snagging this for me.
UPDATE: New smaller box size also obtained: 6 ouches, 4.8oz, 2011.
