juice costs me $36.00 for a 180ml bottle and I vape around 90ml per month. I also use on the norm just 2 LR atomizers per month that cost me $5 each. I'm spending $28 a month to vape. The last time I smoked a cigarette was last October 12th. I was smoking a pack a day of generics that cost at that time $4.25 a pack since I couldn't afford my go to brand anymore. vaping costs me about a 1/4 of what cigs was costing me. Not bad.
Congrats on almost a year off the nasties! My figures were accounting for twice that much juice - I'm thinking approx. 30 ml per week across three devices - but that's just based on a few days' full time vaping. Time will tell. Are you mixing your own juice?
