I would get the 30w and the clearomisers from Myepack. It'll be P&P free, leaving you money for P&P on the liquids. I know it's a fuss, but you can't win.
If you got the istick off Amazon, you could get the tanks, atomizer heads and liquids from vape Escape with some Liquid Core. (?)
Liquid Core : Vape Escape
what type of clearomizers on myepack and how many should I get? Then once you've got the istick 30w and some clearomizers, you've still got tanks, atomizer heads and liquids to get? most clearomizers fit on isticks?
