Was it Williamson Brothers? If so, I really like it. I like it on pork & chicken. It was the only sauce I'd buy until I started making my own.
1 gallon for $9.00 is a great deal, to make my sauce a gallon costs $7.80.
EDIT: Just checked and saw BJ's is selling Williamson brothers by the gallon. They are a GA based place, suprised to see it all the way up in CT.
