The only new gear I have bought recently, besides replacement coils, has been for backups. I am still using my original two Protank II tanks.
Some time back I bought a couple of iStick 40W mods, as I like the compact size.
I use LiQuid juices and buy it 20-30 bottles at a time, because of the international shipping charge. At £1 for 10 ml, it does not cost much more than if I mixed my own.
I figure my vaping is costing me around $0.50/day or so - far less than about $7/day when I was smoking.
