I don't think there can be any volume discount for cigarettes by law. I'm pretty sure tobacconists always make the same amount per pack regardless of how many they manage to move.

That's incorrect. Cartons are sold at a discounted pack price, large tins of lose tobacco are sold at a discounted per weight price.

That might be the case in the US but I'm sure it's not in the EU. As a matter of fact I think most European countries (except Germany) also forbid packets that don't have 20 cigarettes.
