If you missed my post from a few weeks ago, it might be worth heading over to Home Depot. They had 16/4 in-wall rated speaker wire clearance-priced at 8-11c/foot. Just make sure you check the "cut wire" section on the thing that's kind of like a big ferris wheel, because that's where it's most likely to be. Also, if it's priced higher, have them double-check it on the computer... a few others here got them to either discover that it was already marked down electronically & just hadn't been re-tagged on the shelf, or talked them into marking it down on the spot.
