Sodastream gas canister (Newbiggin on Lune CA17)

Hi, Can you make use of two empty Sodastream canisters? These are the non-quick connect type which can be exchanged at Argos which will save you approx £12 PER CANISTER off your total replacement cost. Our machine broke so we had to purchase another which is the quick connect type so these cant be exchanged like for like. We are 10mins ex JN38 M6.
