What I don’t have is vg and pg... hope I’m not taking a gamble
IMO, and that of many others...PG and VG will always be available. So quite a few of us, that I know of, aren't putting in a stockpile of either one now. They're used by many other people for lots of things other than making eliquid.
Companies like Bulk Apothecary don't carry nic base, nor flavorings, nor anything else for vaping or DIY eliquids.
But they carry both PG & VG, because people have been using them to make other things (ie. lip balms, lotions, soaps, etc.) with them, for many years.
If push comes to shove...Tractor Supply sells PG by the gallon, for use with cattle, to prevent a physical condition some can get. Walmart carries VG, though only in smaller quantity (IIRC the bottle I bought years ago was 168mL or 170).
Because of BA's sales or special coupons for regular customers, and because I'm teaching more local people to DIY their eliquids, I have 3 new gallons of VG and 2 new ones of PG now...besides a working gallon of each that I just opened about a month ago. (I start the DIY newbies off with enough of each, and some flavorings & nic base, to last them a month or so, until they order/receive their own). Gives them time to check out recipes, decide what flavorings they need/want, etc, and still be able to make eliquid during that time. If I wasn't doing that...I wouldn't have that many gallons of PG & VG onhand now.
