If you’re big on cost savings and you can get genuine stuff, DIY and rebuildables will net the most. Rebuildables aren’t generally sold in
vape stores anymore, but online they are available in abundance. The huge savings are due to the fact that they use wire and cotton instead of proprietary stuff. commodity materials vastly cheaper than disposables or pods. It costs me less than a penny for a new”pod”, and a dime for the
juice.
