I figured that in the 5 yrs I quit smoking, I would have spent over $14,500 in cigarettes. I have spent no were near that on vape supplies in 5 yrs even stocking up, so I am way ahead of the cost off smoking for 5 yearsthat is why I have not even flinched at stocking up costs, it is a drop in the bucket
Especially stocking up for the rest of my life and if a friend or family member is in need in the future.
I take the long term view. I do keep an eye on what I have spent stocking up but that will be amortized over 20 years. I can vape for the next year without spending a cent. Next year I will need flavors if I want flavors and PG. The year after I may need some batteries as well.
All I am buying now is things I want but don't need and adding to my stock of coils.
