18/8 8-strand Electrical wiring

I have a substantial amount of leftover wiring 18/8 from a electrical project. 8-wire / 8-strand18 gauge signal wire - suitable for irrigation valves/sensors, HVAC or sewage dispersal pump float sensors and other similar application. Had to buy a 75m roll of the stuff but only used ~20m at most. Selling the remainder at my cost of $3/m
