JCPenney has a few online codes available to get the most out of your money.  Here are the codes and what to do:

1) Click Here to shop through - You will receive 6% cash back!  It will only take a minute to create an account and then anytime you shop online shop through them to earn even more money!
2) Click through to get to JCPenney.  I would recommend checking out their clearance section for some great deals!  
3) When you are all done shopping use code BESTCROP to receive 20% off your total!  
4)  You might be able to stock a shipping code along with the 20% off code.  If your total is under $69 use code FREESHIP to get your purchases sent to your local store for free.  If your total is at least $69 use code SHIP69 to have your purchase sent to your home for free.
