I took the information you see below from the official Jcpenney website. I've already collected quite a few buttons and entered in codes to win $5 and $10 holiday certificates to spend at the store. The promotion ends at 11:59 p.m. CT on December 24, 2012, but you may still use the holiday certificates until they expire at 11:59 p.m. CT on December 31, 2012. Bigger prizes may also be won, but the odds aren't as good. The holiday certificates have helped me out a lot with buying Christmas presents especially since money's been tight this year. Hope this helps. Best of luck to all who enter the contest!
