I use Bulk Apothecary and have not had any issues with the quality. On my second gallon of both PG and VG. My mixing slowed down once I taught my neighbor how to mix so have not ordered in a while but have no complaints from my past experience. If my memory serves me correctly, the price with shipping was cheaper from BA.
I have used from Essential Depot in the past as well but in truth, kind of like the VG from BA better. I got an odd taste from the last purchase of VG from Essential Depot. The taste reminded me of what Halloween face paint smelled (not sure if that makes any sense, but that is what I wrote in my notes). Could have been a fluke with my taste buds changing at that time, or just a mental thing and had nothing to do with their VG. In any event, ordered from BA and have stuck with them since.
