Essential Depot is moving to a new facility and reducing their prices by 15% on existing inventory. I just ordered a gallon of VG and a gallon of PG for a total of $50.57, shipping included. With 2 gallons of VG and a quart of PG already on hand, I think I'm set for life. (Now where have I heard that before?)
