Any ideas where I can locate this quickly or companies which may stock something similar. Only need a probably 10 feet of 2 conductor and 10 feet of 4 conductor and really don't want to pay high shipping cost yet again for wire.
I can't offer an answer to the question you've asked as it seems to be a strangely unique wire and I haven't found it anywhere else but I can throw another thought at you. There seems to be an anomaly in their shipping program that forces wire by the foot far too quickly into priority mail yet if you buy the cable sets they ship first class mail. 10 feet of 4-strand cost $7.98 to ship yet you can drop 13 foot lengths of both the 4-strand and 2-strand cables (with connectors) into the cart and they only cost $2.93 to ship. Sure they cost a little more up front but if you play around with some combinations in your cart you just may come up with something you find palatable. And if you can overlook excess wires in a bundle you may find just ordering an 18 foot 4-strand meets your needs. I had one in my last order even though I knew half of it would be used on 3-wire limit switches. (I am not in any sense of the word a purist. Least expensive wins every time.)
