Coborn's Inc. is expanding the company's footprint in the oil-rich region of North Dakota with five new stores by 2014, the St. Cloud Times reports. “North Dakota is a prime market for Coborn’s to expand,” Coborn’s President and CEO Chris Coborn said in a statement. Coborn's opened a Jamestown, N.D., store in May. The St. Cloud-based grocery chain also partnered with Williston-headquartered JK Foods to co-own three supermarkets.
