To get a Free $10 JCPenney Credit - first register for JCPenney Rewards here, then download their app for iOS or Android. On the JCPenney app - enter your phone or email that you used to sign up for JCPenney Rewards to get the points.
Seems like their sign up page is partially broken. Wouldn't let me select month and day for my bday to get extra stuff. Also after u sign up it says u have to spend $100 before u get a $10 credit, so this is not free. Unless u plan on shopping a lot at jcp, I wouldn't bother with this "freebie"
