I have been working on renovations to my Basement home theatre and bought in wall 12 gauge from Home depot (Oxygen free too BTW, not that it matters). It was $0.92 CDN per metre. For our American friends a metre is about 3 and 1/2 feet so that would be about $.26 CDN per foot. Seems like pretty good wire to me and well worth the $$$.
