I save money buy mixing my own liquids....And it took a while to find the cheapest suppliers. As I use mostly VG I also found the Chemists vegetable Glycerine was cheaper than online....I buy Perfumers Apprentice Flavourings and Unflavoured Nic from Liberty Flights UK... It can be bought cheaper elsewhere, however I'm in the UK and dont like to order Nicotine in large quantiites from over seas........
