I have no regrets about stocking unflavored in 2009.
Here is what might happen:
1) You love chocolate-bananna-blackberry. Vaping 18 mg is working for you. You believe one of these scare threads and stockpile a whole bunch of it.
2) You think that you might want quit altogether so to prepare for that event, you stockpile 0 mg nic in chocolate-bananna-blackberry.
3) Months later, the constant urge to smoke returns, so you go to 24 or even 36 mg.
4) You realize how much you miss the taste of tobacco and that vaping chocolate-bananna-blackberry is just not working.
5) You wake up to the fact that buying juice will be more expensive than you thought it would be.
6) You end up with $300 worth of chocolate-bananna-blackberry in your fridge while you continue to vape 36 mg Dekang Camel.
Unless you know EXACTLY what you will be vaping in six months, which most of us don't, stockpiling is an expensive and dumb idea.
HTH,
Dave
