My wife and I were paying @12 bucks a pack when we quit cigs over 2 1/2 years ago, thats 25+ bucks a day. I have spent my fair share on vape gear over that time but no where near the cost of the cig habit. I can say I've spent 3-4 grand on vape gear, we both vape with top shelf gear and have had a great vape experience so far.
I learned early to rebuild my old CE4 clearos then protanks, kayfuns and now subtanks. Making my own juice for the last year has also improved our vape experience since commercial juices have exceptional amounts of sweetener and I can't vape them at all anymore. The biggest plus of me making juice is that I'm not thirsty and drinking gallons of water like I was with commercial juices trying to quench the unquenchable thirst and up all night pizzing.
Its not the money saved by rebuilding or DIY juice, its the quality of the vape experience and hassle free vaping that makes our vaping great.
The ticker on the bottom of my post pretty well says it all, 38,000 cigs not smoked and 21K saved but that is over 2 years ago pricing and smokes have gone up to over 15 bucks a pack here in BC so the cost number is a bit off.
