Our business consists of selling merchandise and services to consumers through our department stores and our website at jcpenney.com, which utilizes fully optimized applications for desktop, mobile and tablet devices. Our department stores and website generally serve the same type of customers, our website offers virtually the same mix of merchandise as our store assortment plus other extended categories that are not offered in store, and our department stores generally accept returns from sales made in stores and via our website. We fulfill online customer purchases by direct shipment to the customer from our distribution facilities and stores or from our suppliers' warehouses and by in store customer pick up. We primarily sell family apparel and footwear, accessories, fine and fashion jewelry, beauty products through Sephora inside JCPenney, and home furnishings. In addition, our department stores provide our customers with services such as styling salon, optical, portrait photography, and custom decorating.
