(Mauston) ShopKo is closing six more stores in Wisconsin. The stores are in Appleton, Grafton, La Crosse, Menasha, Seymour, and Sussex. The closure of the Mauston store has already been announced. ShopKo is based in Green Bay. It announced late last year that it’s closing 39 stores in 19 states by the end of February. ShopKo operates about 360 stores in 24 states. ShopKo has said the closures are dictated by the long-term outlook on profitability and other factors. ShopKo intends to seek bankruptcy protection from creditors next week.
