Yeah, you can often find used wire fencing on C's list. People take down a fence and the wire is still perfectly good. Look for horse fence rather than farm fence (holes are way too big on farm fencing). I've also seen chainlink on C's list--i.e., not pen panels but plain old chainlink.
Take your time if you can and search C's list like a hawk! It will pay off!
Try Freecycle, too.
