I've been buying unflavored 50ml Nicotine at 54mg/ml (5.4%) mixed with PG at $15.99 a bottle. Totally-Wicked quit on me and their sister site is no good. I've visited a number of websites today that only sell flavoring or premixed e-liquid with a huge mark-up. Where can I get a good deal on nicotine diluted with PG these days?
