The only way you'd get speaker wires included is if you bought a shelf mini-system or a home-theater-in-a-box (HTiB) I think. Most speakers sets or pairs don't come with speaker wire. One of the best place to get it is at Home Depot for < 24 cents/foot.
I'm running my SVS right now with a 25' cable that cost less than $10 at Radio Shack. Someday I will get around to making a nicer-looking cable with some Canare stock, but the cheapo solution works fine right now.
