Well. I haven't put it into numbers, but if I must, I must. I was a 5-10+ analog-a-day smoker, rollies, a pack (hey, it was organic) cost $14, and lasted about 10 days. I don't remember my last cigarette, but it must have been 3 months by now, which would have been $42 per month, which is $126. I've spent well north of $500 on stuff since then, and I don't really see much of an improvement for the future. I'm still figuring out what's good, tasty, and cost-efficient.
I am pretty much done with the initial outlay, from eCig, to Spinner, to ProVari, with two clearomizers, a R91 and IGO-W. Also included is coil and wick making material. Many thanks to ECF for all the info to make the right choices!
Now I'm exploring juices. The month of May was close to $100 on vapemail, but I'm already down to 3mg juice (mixture of 6mg and zero). I'm a chain vaper, so I go through 30ml in about 3 days. I love my LVS (Local Vape Shop), so I stop by and get some different juice every week, which works out to $120 a month on juice on top of the vapemail. That's $220 a month. Yikes!
