The pricing for Sky customers is £18 for one, £22 for 2, £26 for 3 or £27.50 the whole lot.
So as others have pointed out, the only real price saving is by having one or two. At that point, it's a close call as to having the whole lot. Which I'm sure is no accident.
But that's back to scheduling flexibility again, of how they will manage multiple events of one/two sports at the same time. Rugby and cricket I see as the two problems, where you can easily overlap games and currently have 5 channels to schedule across. Now you only have one - and will the red button be the same PQ etc, as a broadcast channel???
