I'm Awesome
No I haven't yet but I probably should, I'm sure they wouldn't mind selling it. I'm in Wright City, right outside of St Charles county. I only know of audio ace and auto styles that's near me.Have you tried any local audio stores? There's a couple around me that keep spools of various colors of 1/0 gauge. Might be the way to go if you only need a few feet.
Not sure what part of MO you're in but D&M Sound in Columbia is one store that comes to mind.
