Highly recommend you buy the 7 gallon aquatainers on Amazon and have them fill those. Better handle, a spout, and obviously holds more. The 5 gallon containers they sell spill everywhere when I try to pour from them. They’re awful.Suggest you search for NAPCO store. The one in Houston (Spring, TX area) sells to the public 3 days a week in 5gal containers. This is the best bulk store I have found.
But yeah, <$2/gallon for fresh 12.5% is impossible to beat.
