now i have to know your source for that great price,, i got my glycerlin for $39 but only 5Liters. do you have a linkThis year as I am running two of the machines I invested in making my own 30% / 70% smoke fluid from pharmaceutical grade Glycerin (costs me $39 per 20 liters rather than $150 from DJ City.) I also buy the Gazillion bubbles from Big W way more cost effective than DJ city.
