I definitely think it would be a good move in the right direction. The e-cig community has EXPLODED in recent yrs from something barely heard of, to the big new thing. I feel jumping in now would be the best decision in creating a loyal customer base that stay true to you when others decide to finally jump on the bandwagon. I really don't think e-cigs are going to go away. They are pretty much here to stay in some form or another.
And I definitely agree with Fishegg, having a juice vendor right down the street is any vapers dream, and to be in such a big area as CHICAGO....thats just a perfect equation for success.
I personally am going to also put as much money as possible into the first e-cig stock i come across..i forsee it have returns of the likes of Apple!
GO FOR IT!!!!
