J.C. Penney is borrowing ideas from supermarkets and warehouse clubs as it launches its new marketing campaign. Penney means that literally. The company plans to sell some of its best basics for a penny, starting with items from its $1 billion Arizona brand. Some promotions will be buy one, get one for a penny, and some items will be 1 cent, without another purchase required. The retailer says it’s investing some of its marketing budget on freebies.
