I have a relative who is a Pharmacist and was wondering about asking him if he could source PG/VG nicotene base liquid from him for a better price than I might be able to get it from one of the normal suppliers. Before I ask him about it I was wondering if anyone could advise me what I should be asking him for. What I mean is what should I call the base when I pose the question so that he understands what I am asking for?
