So it's 15.99 quid per 18 pack of wifebeater
On an average day a grown marsh boy of your stature should stay hydrated with at least 6 cans.
18 divided by 7 is like less than 3 so that won't work. So a more appropriate amount would be 2 18 packs per week. Resulting in 5 cans a day over the week, which puts you at a deficit, but I believe that our complimentary free selection of 2x snacks a week should just get you over the threshold.
That would equal, in crude math, about 1872 cans a year with a bi-monthly 'emergency stash' of 6 extra cans for the hard days.
So you'd probably have to consider stripping on the camera as well to ensure that us trusty RB'ers can justify the weekly outlay of a collective 40 quid, allowing financial wiggle room for the occasional pack of digestives and an expired cheddar.
Paint stripper not included.
