I bought a gallon of 190 proof denatured alcohol from Alliance Chemical - alliancechemical.com
Ethyl Alcohol Denatured 190 Proof - One Gallon - in (4) 32 FL Oz Bottles. $36 and free shipping
Ordered first thing in the morning. Received notice of shipping via UPS two hours later.
I like the smaller bottles since I don't expect to use a gallon for quite a while.
Best deal I could find anywhere and so far the service has been outsanding.
