The path from the parking lot leads you across the porch of the General Store. This late 19th century building once stood across Colvin Run Road from the mill. Storekeeper Mark Cockrill stocked general merchandise for the farming community of Colvin Run and for patrons of the mill.

Today, examples of merchandise that would have been sold during the years the store operated, from the 1890s to the 1940s, are displayed on the top shelves and hung from the ceiling. The general store continues as a mercantile establishment, selling grain ground at the mill, "penny" candy and sundries. During the Children's Holiday Shopping event, held annually the first weekend in December, volunteers help children select and wrap presents to surprise their friends and family.
