So, just want to ask a few questions. Maybe some will get better info than I pursued prior to "looking for best price".
How many PG and VG Manufacturers are there ? --------I suspect there are quite a few, most outside the US.
What Grade should you look for ? ----------------USP
Who makes a smoother base ? Or a sweeter base ? -------------- Might check into VG main veg. used (whether it be olives, palm trees,coconut oil, soy,etc. products). Would not be surprised that the USP grading may have taken the taste and/or
sense of smoothness out of the equation.
Can you get Quality and Price ?
