Went to local tesco,Luton and they had 8 packs of extra downs from 1.50 -50p
50p was for the blue packets,
51p for green packets...
Cant remeber the rest but they were all 51-55p .
Wasnt much stock as it looked like someone had took the whole box but if you in your local tesco have a look.
If any one can confirm its nationwide please do .
And i though it was cheap when i got 8 for 1.50
