UPDATE: I finally ran out of the 2 cases I bought last July. The good news is that this is still commercially available. Rite Aid stores are carrying the 12 oz aerosol can, and you can buy this from Drugstore.com and others. The bad news is that the price ranges from $6.25-$7.99 per can, with shipping on top. The price at Rite Aid is $7.99 as I write this, so, for now, I plan to shop there.Here is the Blairex web site - it has links to Drugstore.com:
