I get Hi Life 60% from Sainsbury's.

I think it has been in short supply recently - and think its because they are changing the ingredients. They have already changed the ingredients in the single pouches, I had to buy some single ones a week or so back because they didnt have the boxes of 12 - and I noticed the different ingredients (havent got any single pouches currently - and can't remember exactly what the new ingredients were!) . But when I bought the boxes of 12 this week - the ingredients are still the same - I'm guessing they'll be changing them all over ultimately though
