Xfinity Extra Channel Lineup

So Comcast is now offering a deal for me using what they are calling the "Xfinity Extra" channel lineup.  But then you go to where it takes you to see the channels in this lineup, it merely goes to the default screen showing Basic, Starter, Preferred, etc, but no "Extra" channel lineup, which is supposed to have 125+ channels.

Does anyone know where I can find a list of these channels in this lineup?
