Do you need to rent/buy the bottle from Calor? If so, how much does it
Kind of neither - no deposit - you just go in & ask for a 3kg bottle of CO2
& pay 'em the £15 & off you go. When its empty you take the old one back &
get another for another £15. There is no paperwork either so theoretically
you could stockpile a heap of empty bottles by not taking the empty ones
back I suppose - but why would you??? Which is why there is no paperwork &
no deposit I guess!
