You can still get them but prices are pretty outrageous compared to before. As a result of that a lot of the smaller companies have died and a lot of the small independent neighbourhood vaping shops have closed.
I have just checked my bulk order from before the tax… I paid 30€ for 1l 50:50 base. Today you pay 35€ for 100ml of the same (same shop of course).
Edit: the irony of the whole thing is that it’s now more economic to use high nicotine ready made liquids and to not use sub ohm coils to reduce liquid throughput… Great work lawmakers!
