How would I do it?

Hey, so over the past few weeks I have noticed a group of korean/asian people smoking plain packaged marlboro cigarettes and today I decided to ask a where they get them from, and he struggled to understand my english, and said that he gets them from overseas when he went there. But I find this hard to believe unless he goes every week because always at that spot their are koreans smoking plain packaged marlboro's. I said that and he then said you can get them from a Korean place down the road, I had a look down there and there were none that sell cigarettes and if they did it was with the ugly "cancer, lung cancer ect" advertisements on their.

I was wondering, how these koreans are getting these cigarettes, where from, how much they cost, and if I can get them as well?

Anyone with any idea would be greatly appreciated

Regards
