BlackSnow is now my favorite brand. I think it is as good if not better quality wise at 1/2 the price. Before I found locally here is where I used to buy it for around $10 www.alamirusa.com
. I used to buy 4 cans plus shipping for about $50. These guys are the actual importer/distributor for this brand. The only thing the site is not setup for e-commerce so when you order you give your name and email/phone and someone will call you back with a quote. You can also call the number directlly. My other choices are Tonic and Fusion ( in the tin, not the pack). Very similar but cost more online.
