I don't make anything fancy. Just use Capella flavours and shake n vape. I reckon on just over 70p for a 30ml bottle. Even my wallet can handle that......just
Edited I just worked it out again. It's closer to £1 for a 30ml bottle.
2ml a day is about what I get through, mostly on Kayfuns and Triton Minis at about 13ish watts. I do have one subohm tank which I have the occasional puff on but not enough to seriously ramp up my juice consumption.
