Natural Grocers is finishing up its move into the former Staples building in Bismarck, and the Colorado-based health food chain plans to open Sept. 4.

The store at 840 South Washington St. is scheduled to open at 8:30 a.m. that day with activities through the day including vendor demonstrations, a gluten-free muffin sampling, an ice cream social and a gift card sweepstakes.

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 will be the third Natural Grocers store in North Dakota. Fargo and Grand Forks are the other locations.
