I ran across this on a Bears message board. If you are a current DirecTV Sunday Ticket subscriber, you can go to your account on their website, click on "change programming package" and you will see an option for the Superfan package for $0.00. I believe this gives you the redzone channel, HD games, etc.
Anyway I clicked on it and now my DirecTV programming includes the superfan package and the billing activity since my last statement shows the charge for it as $0.00. My guess is they decided to give the rest of the season superfan package for free, anyway I'll know for sure this Sunday.
