the worst (and best) place to buy cigarettes i've been to is singapore. last time they were like 12€ per pack in the city and 1€ per pack in the duty free.
I live in Texas. For a pack of Camel Turkish Golds I pay 7-8 bucks they ain't cheap but I like how they hit/taste.
If I'm on a budget or if I'm really fucked up I get kamel red lights and they are like 5 bucks not a bad deal they are smooth just a little more harsh than the other camel Turkish golds. But like I said when I'm fucked up I like harsher cigarettes.
