IIRC, I did a rough calculation.. including flavors of my 50mg nic salt juices. I think it was about $1.25-1.50 or so per 30ml. Itll go down obviously when I decrease the nic, but even right now it's huge savings
Sounds about "right", Bark, including flavors and bottles. And yes, bottles are reusable many time, so pro-rating them out it might add 1 or 2 cents. Or less.
