It appears FF36 is no more - starting product is FF74
Just got off the phone with COTS who confirmed it. I was asking because looking at upgrades on my PN account I was offerd FF36 at £28.99 on an 18 month contract (I'm currently on 40/10 on the Trial). Given this is somewhat above the FF74 offer it didn't make sense. My account offer is out of date.
