Im wondering if I should buy more. I could afford to spend another 100 on another L of Nic, before it gets taxed to 5k for a 100mg bottle.
I don't know where you got the nic base that was $100/Liter for the 100mg/mL. But there IS 100mg/mL nic base that's very popular, very good quality, etc. currently available for only $44.99/Liter. Many of us had been buying and using the House Brand 100mg/mL nic base from Heartland Vapes for years...well before people started stocking up on nic base for the longterm.
With the current FDA mess, attacks on vaping and outright lies about it, the likely future problems with the availability and price of nic base, etc....many more people have prepared for the future. They've bought, rebottled into glass bottles with the polycone caps, and stashed numerous Liters of nic base in their freezers. A very large number of those Liters have been Heartland Vapes House brand nic base....because of its quality and its price. There are still a few other US vendors who sell the 100mg/mL. However, none of them come near Heartland's price for it, which really helps stretch their $$ further and enables them to buy more.
