People lined up early Wednesday to get a peek at the Natural Grocers store on South Washington Street in Bismarck. The long line of customers stretched along Washington Street from the Bismarck Elks Lodge to the front of the store that opened at 8:30 a.m. The Colorado-based health food chain remodeled the former Staples building. Natural Grocers is a specialty retailer of organic and natural groceries, body care products and dietary supplements. It operates 152 stores in 19 states. Bismarck’s location is the third Natural Grocers store in North Dakota. Fargo and Grand Forks are the others.
