I had planned on doing the same. Didn't make it through the day since Evape got more tanks in stock. Lol. Had to order another and 3 more packs of coils.
The main thing is to not turn vaping into a hobby, as I did, if you want to save money. I enjoy it and use everything I have but I don't recommend it for anyone that is trying to save money. Cigarettes are $8.50 a pack here though and I used to smoke 3 packs a day so I could figure that I probably have saved money!
My wife for a while made snide comments about the ever growing vape paraphernalia on my bench. But I found this little phone app that shows some really neat info:
Quit date: June 1st 2014
Not smoked: 11286 cigs
Money saved: $2539.35
Vape Expenses: $1146.89 I went crazy and (also buy starter sets 10 at the time Kanger EVOD Megas to give to anyone and everyone willing to take one, all included in this figure)
Still left an extra $1392.46 in a little over 7 months which has led to a LOT more dinners out for her too!
Since I now no longer smell like an ashtray and am even allowed to vape anywhere in the house (she sez I smell like a renuzit air freshener now) and health is improving to the point even she notices, much less me being able to smell and taste again. And make it upstairs without being winded, she is now on board whole heartedly!
