I've always DIY, too. But I have to go the cheaper route, walmart food flavorings (no oils or sugars). I use the humco brand VG, also at walmart, $2.50 for 177ml, and buy nic at 50mg and dilute it down, use an e-juice calculator to get it to around 14mg with the flavors and vg. May be a bit weak on flavor sometimes, but it works for me, and I have enough supplies to last me a couple of months at least.
*did I already say all of this? must be getting tired lol*
What % of the flavor do you use with your VG base? 10%, 20%? Just curious because in a pinch someone could go buy some VG and flavor get them thru even if they run out of juice while waiting for a shipment. I see this happening to alot of folks. I always keep PG and VG around so I have a good supply to vape. I have not tried diluting the high nic %'s yet, may try that later, but I was worried I would not get the level right down from 50 or 48. bnrk
