Following yesterday's announcement that Sirius Canada is partnering up with the CAA, it seems that the American counterparts are doing the same.

AAA members can get a 20% discount, free shipping, a free month of service and free activation. The AAA website changes according to what ZIP code you're in, but as far as I can tell this is a nationwide offer.

Thanks to Steven, Jeff, Peter and everyone else who sent this in!
