This shop does 3 bottles for a tenner which isn't too bad I guess, and they don't sell bigger than 10ml bottles so I can see how the price can add up, I was spending about a tenner a week on rollies, not including papes (never bought filters though), so when I inevitably start vaping heavier, chances are it's going to be costing about the same, so I would probably appreciate a cheaper liquid supplier, what do you use?
So you were on the rollies too.... sounds about the same as me then.
You don't necessarily end up vaping more liquid, but the higher powered equipment often means dropping down a strength (to avoid too much Nicotine in one go) and then vaping a little more because you've dropped a strength. (I know... sounds a bit crazy...)
I use the onepoundeliquid LiQuid online shop.
