It always says when you read the restrictions for the sale, what areas qualify for free shipping. Most, if not all U.S. online stores are free shipping within the U.S. only - story of my life around here, but I have a friend in U.S. who brings stuff back for me.
I just went on JCPenney website to check for you, and there is currently no free shipping being offered. Just click on Customer Service on top of page to see shipping rates, or call to inquire, but no free shipping that I can see, so I can't read the restrictions on that promo at this time.
Happy shopping, Tiger
