Hello I have been vaping for about a year now, but just recently have started looking elsewhere for my juice. I had been buying them from a kiosk in the mall and have been paying an arm and a leg for them. ($24.99 for 15 ML) I was wondering what the difference from a primarily PG base liquid is compared to a VG base liquid??? I noticed that the bottles I bought from the mall where thicker then the new bottle I just ordered from the internet. Please help me.....
