JC Penney has their Black Friday ad on their site right now to preview. The ad shows that JCP will be giving away $10-off-$10 coupons out at the door, while supplies last, and of those, one in every 100 coupons will be a $100-off-$100 coupon. (Nice deal if you get it!)
JCP stores open at 5pm on Thursday (Thanksgiving.) The $10-off-10s are good Thursday and Friday, and if you’re lucky enough to get a $100-off-$100, those coupons are valid Thanksgiving through Dec. 24th.
