So was looking on the internet where to buy FLV in the UK and stumbled across theecigshop and they are selling different assortment packs for just £20. I have no affiliation with them just thought I would share this all with you.
EDIT Woftam : I fixed the URL for you is is now correct and safe
I was begging them twice in the last 2 months for international shipping; volunteered to be their guinea pig. No luck. I was buying flavors at 6+ different vendors in the UK until the Brexit, atm my only reasonable option is Chefs with very friendly shipping (who knows when others will adapt).
