Today is Black Friday, the biggest shopping day of the year. Black Friday is generally speaking the largest holiday single shopping day nationally every year. Many local Pella stores will be offering great deals throughout the day. Karen Eischen told KNIA/KRLS that many stores in Pella will be running Power Hours from noon until 2, offering additional discounts on certain items. Some stores will also be offering extended hours of operation. For hours you should call retailers.
