In reply to splat2million:
Decathlon should have the Primus canisters, although around there stock is not always in store and you are unlikely to find anyone who will tell you where to get it if they are out (probably will get the sack for recommending any other shop than Decathlon or something that would seem strange to us). Alcohol is available as fuel from the bigger hardware stores, which stock various concentrations up to about 96 %, watch out for the common 70 % alcohol in general stores though which doesn't burn as well as what you will find in the B&Q style shops.
