JC Penney did a good job with their holiday ad in integrating social media. They are also going above and beyond by giving an option to signup for email offers and also text messages. On another note, during a recent visit they were also using FourSquare in their marketing by offering a special if you checked into the store. It saved me $10 on my recent purchase. Overall, I think they are doing a good job with their social media marketing strategy.
