There is not a one of us that hasn't made a mistake or a poor purchase. I consider myself one of the lucky ones and I managed to spend $1000.00+ (lots of DIY flavors)in the first 3-4 months. It took me 6 months to break even and now I spend roughly $12.00 per month on hardware and juice. Now, if I change my hardware that all goes out the window but for now I am perfectly happy with my 3.7v 900mah PV and I DIY my own 0mg juice. I figure in two months which will be my anniversary I will have saved $700.00 in my first year of vapeing. Next year will be real cheap if I stick with the same hardware and it will only cost me about $143.00 for the whole year! ...............Notice I keep saying "stick with the same hardware"? I have my eye on a provari as a one year "Happy vape/birthday" present to me. There goes the big savings. I figured my cost will be about $33.00 a month then which is still a heck of a lot better than the $160.00 I was spending on analogs.
