If I stuck with a simple Ego style battery and bought only liquid and atomizers at the rate I need them, then yes, I would certainly be saving money. However it seems that I have at least 1-2 pieces of vape mail headed my way each week. I haven't done any math but I am positive I am spending more money than when I smoked analogs. Oh well though, it's a fun hobby and I love getting vape mail... it makes me feel special.
