I was skeptical at first until a friend of mine broke it down for me... vaping to replace analogs (not as a hobby) is expensive AT FIRST. I dropped about $70 - $80 on my first day. Bought an iTaste VV 3.0, two EVOD Glass tanks, and three 15ml bottles of juice. It's been nearly a month now and the only money I've spent so far is $7 on 5 replacement atomizer heads. I would smoke about 3 - 4 packs of cigarettes a week, and at about $5.50 a pack, that's ~$88 a month. So the first month was approximately the same price as smoking analogs, but considering what's left of my initial juice purchase will probably last me close to another month, the savings will pile up REAL quick.
