Hmmm... when one is first starting, there's a need to get a nice multitude of devices. For one thing you need to try vaping in a lot of different ways, to know what you like best, and you really need to have backups for your backup's backup. I started vaping the first of last February, and by May, I had bought an eRoll, 2 iTaste vv3s, a Sigelei Zmax, an ego twist, and an ARO winder, plus a half dozen T3S's. The ego twist was a cheap knockoff and became defunct in pretty short order, but all the other stuff (except the T3S's) still works and gets used, though the Winder, not too often, and I now also have a Vamo v2 and 2 mechs, and a 3rd vv3. Too much? Nope. I can get a decent vape very easily, and have several flavors loaded up and ready to vape at any time -- in 3 different kayfuns and a Magma, and even a cartotank if I want, though I got tired of the expense of buying cartos.
Saving money is not the #1 objective, even though my own budget is extremely limited. The Prime Directive, if you will, is to happily refrain from smoking -- and save some money while I'm at it. Saying "just quit" in the name of saving money is irrational, and in the real world, will not happen, when one is truly addicted to smoking -- it's either vape or smoke, and vaping is both cheaper and healthier, so that's my choice.
When I smoked and money was tight, it was the food budget that took the hit, never the cigarette budget.
