Doesn't anyone here ever go in a supermarket? A six pack of 500ml
mineral waters costs about £2 (supermarket own brand). Buying in bulk
reduces the price. Morrisons have an offer currently on, I think,
Volvic in 5litre bottles for about the same price - not that I'm
suggesting you take a 5l bottle to work, just refill a smaller one.

Indeed, I fill my £1.99 water bottle from the powwow water supply. I'm
thinking more of cases where you are caught unprepared in town. Carts
along the river, for example, are known to rip tourists off.
