As an underage smoker (like 1966 and on) in a place where the stores tended to be strict about proving you were 16, I had to resort to any of several unattended vending machines (and I knew where they all were). But this meant I had to pay a bit more for a pack than I would have OTC. Maybe 45 cents instead of 40. A few years later, after I was "legal," prices had gone up a bit, and they were 52 cents a pack at the store. But I seem to recall paying $4.50 for a carton. I've lately noticed that the carton price discount (always amounting to the price of a pack or so) seems to have disappeared.
