I was just checking out Tractor Supply online and notice they have a gallon of USP PG for about $22, I have one locally and I'm running out. I have always ordered from Essential Depot online and have never had a problem with it, but I have only about 100ml left.
Just wondering if anyone notices a difference in quality between the two? I can wait if I order online, but at 12 bucks a piece for two quarts at Amazon I can get double that at a little under that price at Tractor Supply and have it today.
