I don't follow that price sheet very well. What I want to do is compare the price of cable with (ground, white, black, red, blue) against the price of cable with (ground, white, white/red, black, red) to see if there is a difference in pricing or availability based on the colors. These 2 types of cable are identical except for colors (substitute between blue and white/red), so they should be about the same price unless there is some market issue involved. I'm trying to find out about that.

I called a local electrical supply store the other day. They don't even know what I am talking about. They don't carry Southwire, either. Maybe Southwire is the only source of this?
