The mill shop is open to the public on Saturdays from 10 a.m. to 4 p.m. Various types of flour, baking products and baking supplies are sold. Many home bakers have found their way to the mill to bake bread, pastries, sourdough bread, speculaas and more.

With sufficient wind, De Vriendschap is operational a few days a week as a traditional flour mill thanks to a passionate team of volunteers. As a working museum, the mill can be visited free of charge for the public every Saturday. At the mill, various ecological grains are processed into flour, flakes and mixes using wind power in a traditional way. They do not only sell this to bakers, restaurants, fellow millers and organic shops, including a supermarket, they are also available in the cozy and well-stocked mill shop. In addition, many other products are available in the store.
