I've never used it myself but there's this site: https://thevapetrader.uk/
There is also a UK version of the Reddit sub: /r/ecigclassifiedsuk/
I just stick to the Classifieds on here to be honest.
Hi
Are u looking to but something specific? Or sell?
Dee
get a bit more involved and after 100 posts certain new sections of the forum could be come available to you. dont spam though as mods like nothing better than wiping post counts from spam posters.A bit of both to be honest. Even if not looking for something specific you could find some decent deals and buy anyway.
