Well e-cigs are a good alternative to regular cigarettes. If I am smoking e-cigs then I don't need regular ones - try www.smokingeverywhere.com for ordering e-cigs.
Ask yourself if you really think its reasonable to pay $150 for 2 x 3.7v batteries that connect to a hot wire and an LED because there really is nothing amazing or expensive about the technology that make these work though due to the newness of the product, Smoking Everywhere and other heavily marketed brands have been able to tempt consumers to part with big money at mall outlets and elsewhere.
The kits go for $10 - $15 wholesale from China and fierce competition online has sellers giving them away for as low as $35 sometimes or for an average price of around $50. There is also a far wider range of devices online as suppliers are having Chinese manufacturers create more advanced modifications to best compete. The best e-cig out there right now would you believe is one you can make on your own from a cheap flashlight!
I've become very taken with e-cigs and have quit tobacco effortlessly for almost a year now using them. The FDA though is very confused about them. They are stopping some imports but allowing others...some say it's do to with the packaging (don't market them as cessation devices!- nearly all the chinglish manuals do). Hong Kong recently outlawed them even for export so this has hindered supply in recent days. I set up a slinkset site to follow the news at http://www.e-cignews.com you can also find a list of all the stores there. I swear I add at least 1 new one a day.
