Just Triple your nic level and add a 2oz (60mL) doubler to your order next time. TV juice goes up to 48mg/mL on the nic, so as long as you're vaping around 18mg (actual diluted nic would be 16mg in this case), you're good to go. That'll net you 3oz (90mL) of juice for about $30, which is crazy cheap. If you're good with approx 10mg nic, the prices are even better at about $35 for 5oz (150mL). If you do it right, TV is about the best deal out there. And...the juice is good.
Plus, AC is madness...you'll see.
