If you're looking for just straight VG with no nic and flavors health food store is a good bet. I
buy my mixed VG from
American eLiquid Store It's my favorite VG so far.
Cignot and
Cigtechs also have VG, I've got an order on it's way from cigtechs, pretty excited about the gingerbread flavor
I didn't care for any of the flavors I got from Cignot so far sadly

I bought the RY4, chocolate, almond, Shaddock, and pepsi. The RY4 is the only one I can stand so far. Still have the chocolate and pepsi to try. The shaddock wasn't
bad it just was allot more lemony than grapefruity (nobody said it would be grapefruity, was just hoping

) But they're a nice vendor, very quick on getting my goodies to me and good prices.
