Sure, it does. You just have to have a little self-control. Though I am speaking to a bunch of addicts here, so....
Here's how you start to save money, buy 2 LP Reo Grands and a couple of bottom fed rebuildable atomizers and you won't want to buy other devices. Then you're just spending money on juice, kanthal, and batteries.
Until they start putting DNA30 chips or something in themThen you need a whole new mod xD

However, I don’t see myself becoming a hobbyist with vaping. As much as I like the experience of vaping, I don’t really have much of an interest in DIY’ing liquid, mech mods, coil building in an RBA, or even recoiling. Of course I’ve committed to learning to build coils for the KFL+ I’m planning to purchase, but I suspect that’s as far as I’ll go.
Oh dear God an app to keep track of everything I have spent . No, I don't think so, the app would blow up with such high figures. Ignorance is bliss when it comes to what I have spent.
