I have been vaping since early 2008... Been through too many two and three piecers.. mods, cartos, clearos, customs, and the list goes on and on... Not to mention e-juice whether pre-mix, pre-fill or what not.. I DIY now, and that seems to be the most efficient money-wise. Overall, I have probably spent in the neighborhood of $5000 but based on the amount of money I spent on analogs per year..... I have been quit for six years using e-cigs , smoked 2 to 2.5 packs of analogs per day when I was smoking at a cost of roughly six dollars a pack... And at just 2 packs a day over six years I would have spent over 26 thousand dollars, So I am not worried about what I have spent on my e-cig stock.
