Check your emails- JC Penney $10 Rewards Certificate YMMV
There was a $10 reward certificate available to print. I double checked to make sure my account wasn't hacked or something because usually you only earn them when you buy items at JC Penney. Looks like maybe they just issued a freebee reward to try and generate sales. It's a $10 off $10 or more purchase with usual exclusions.
I'd assume you have to already be a rewards member to get one. Good luck!
