For me, the price was not why I began vaping, my health was.. the price was only a bonus really, that I could try it so cheap.
Now, if it hadn't been so cheap, I might not have tried it, in all honesty, but it was and I did so all that is a moot point.
I began though, for my health. I continue, for my health.
That said, I cannot say I won't ever smoke again, apparently in high adrenaline situations I can smoke up a storm yet today. (I did experience a smoking set back after almost three years of vaping the other day) but, it made me feel ill, made my mouth taste like something curled up and died in there, and generally speaking isn't really something I want to do again (although we cannot discount addiction and addictive behavior apparently) it's certainly not something that looks appealing to me after a 32 year addiction, regardless of the price tag, and I cannot see myself going wow, smokes are cheap again so I think I'd love to stop being able to breathe now! ..
Yeah, just not going to happen like that.
