If you want to order some, you can order less than a case from Graf & Sons in Missouri, however, I found J&J PyroTechnics...a master Goex Distributor in PA to be so low priced I buy it by the case from them.
Last year they delivered a case of Goex to me here in Raleigh, NC for $220.
They'll mix the 25 cans any way you want...I wanted all 3F so I got 24 cans of 3F and 1 can of 4F priming powder...works out to $8.80/lb on your front porch.
