I've heard pg and vg can be bought in regular stores. Does anyone know what the names of the products are and where they can be purchased?
Anise, this isn't a regular store but may be of interest to you.
Check out Bulk Apothecary (out of Ohio) they sell Nature's Oil VG/PG. Good quality product and they ship quick (my exp). I have been using their VG/PG for a long time and never had any issues. I'm pretty sure they are listed in the DIY sub. I know several folks who use them are happy with their product.
VG:
Glycerin
PG:
Propylene Glycol
Their VG in 16oz is $4.13 US and the PG 16oz is $4.71 US.
The 10 lb VG $14.60 and 8 lb PG $18.52 come in gallon sized containers (I get those).
Like Baditude said Bull City also carries VG/PG but it is more expensive.
Hope that helps.
Just don't buy the 45000 lb tank truck for $24,322.50 while sleeping or we'll have to split it.
