Do you think Big Tobacco has thought of this trick yet ?

I was thinking if cigarettes are about $7 per pack wouldn’t it be a smart business savvy idea to sell them for $4 a pack with each pack holding ten instead of twenty cigarettes? A lot of people who only have $4 would think, “I don’t have $7 but I can afford $4” Do you believe a lot of people would buy them? The tobacco companies would make an extra .50 over what they make now.
