The following links are to vendors of PV supplies that I have personally ordered from. Their presence on this page can be taken as an indication that I have been happy with their service and products.
In no particular order UK vendors are:
Safercigs: UK supplier of the Vision eGo (Stardusts) – my current favourite clearomizer. Daz is a nice guy who is local to me, who went out of his way to deliver an order personally. Top service!
Alba Vapours: Some interesting e-liquid flavours.
Vapour World: Excellent value e-liquid supplier.
Ecig Wizard: Super fast free delivery and home to some of the premium US e-liquid brands.
Liberty Flights Well regarded UK vendor who I purchased my first PV from.
Vapist’s Vapours: Home of the legendary Bananacake eliquid!
Vapourhut: UK vendor of Mister-E-Liquids
This list will be updated as and when new suppliers are used. When placing orders remember that many of these suppliers have discount codes available, which can get anywhere between 5 and 15 percent off the price of your order. A quick Google search should find there for you.
