Lucky Strike are also popular (usually get them in vending machines in nice bars in the UK) - but to be honest, if someone is a smoker and their usual brand isnt on offer they'll smoke the local fags, so my advice would put a markup price on your locals brands rather than selling more expensive ones like Malboro - it will be a lot more profitable...
People living on council estates are consumers too. I would assume the best survey would be to ask the leading manufacturers,which brands they produce the most due to demand in the UK?
Just shows who the majority of consumers are...
