well i cant see this posted so here goes...
For some reason Tesco have reduced the price of the big value 12 pack (usually about £3.90) to the same price as the 6 pack. (£2.29)
it is then on 3 for 2 so getting 36 for £4.58
works out to 12.7p each (equivalent to 76p per 6pack)
no idea how much they are anywhere else but this is definitely cheapest i have ever seen and compared to the others on mysupermarket 36 would cost £11.94 elsewhere atm.
cant see this on my online tesco (think varies per area) but is in my local store and is listed on mysupermarket too.
deal button goes to the generic 3 for 2 which may or not show the 12packs but ends on 18th
