Each day until Christmas you can win instantly, but even more likely, do the COLLECT & WIN option to guarantee a prize:

Everyday you play, you’ll get a Collect & Win game piece. Fill up an entire week on the Countdown Calendar to win a $100 gift card from Kmart or Disney

I started this last week and already have 9 game piece’s on my calendar.  You get at least one piece per day, 2 if you invite a friend.  If I make sure to play everyday until Christmas then at least one week is bound to get full, and I’ll get $100! It only takes a minute; totally worth it.

Also, make sure to check out K-Mart’s deal-of-the-day offers they are doing each day until Christmas.  I get them texted to my phone, so I’ll be sure to post them daily.
