Hi all
The NHL have dropped the price to $69.95USD for the remainder of the season - including all playoffs and the Stanley Cup. I use this through the lap top, but it works on my iPad and I assume it will on the PS4 too.
Its a 30% discount on the initial price, but keep in mind almost half all regular season games have been played.
Still a decent deal for the pointy end of the season. There is no blackouts in Australia, but make sure you register using your AUS address.
FYI - they usually drop it once more just before the playoffs - but no guarantees from me.
I think they've dropped it down to US$25 the last two playoffs, but as OP said, can't guarantee they'll continue that.
