It's night and day! I smoked a pack a day of camel filters at $7.50 that's $52.50 a week. My initial cost of everything was $100. After two weeks I'm equaled out, after two weeks all I need is e liquid which is $6 for 10ml which is equivelant to ONE CARTON! So after the initial two weeks I spend $6 for every $75 I would have spent on analogs. I think it's pretty plain and simple, ecigs are wayyyyyyyy cheaper. Not to mention the bills the won't have to pay for lung cancer treatment!
