i grew up in the Glasgow area of Scotland, we could buy single cigarettes for six pennies and the cheapest pack was either 5 woodbine or 5 senior service at a cost of around two shillings,the last pack i bought was 24 royals at £8.30 from a gas station
At school i fell in with a group of smokers and we would each take it in turn to steal a 20 pack from a store each lunch time.
