I contacted Comcast today and asked about year-end pricing for Center Ice. Right now it is $109 but was told it will be available for $49 if you order after April 5th. It will be good through May 17th, which takes you through the 2nd round of the playoffs.
So if you want to watch the non-local playoff games that are not nationally televised, Center Ice may be an option for you if you do not have it now. I do not know if this offer is just a Comcast deal or not, but I would think this offer would be available to other carriers as well.
