Inexpensive XLR cable for SUB

I need a 40 foot long XLR cable to connect my Fathom F113 to a second F113 and the only output is XLR. I see bluejeans cable has inexpensive long runs of RCA cables but where can I get inexpensive long run OF XLR cable?

They have pro audio XLR cables for cheap!

They come in long and short lengths and are perfect for home audio.
