I think this price is the lowest I have seen for a very very long time.
There is a 2.99 delivery charge for 1 pantry box.. . One 4 pack fills up 9.3% of the box so potentially you could get 10 of these in 1 box.
This would make total charge £21.69 for 40 cans of John Smiths delivered.
This may not be the best Beer in the world.. so no cold for the brand of beer please.
EDIT: Price just been further reduced from 1.87 to 1.82... so even cheaper!!
Another price reduction. New price now £1.78 (£1.01 / l)
