It is curious what's happening. Yesterday I called Best Buy and they told me which stores had the specific one I was looking for. Since it was a long drive for me, I called this morning to verify the store still had them. I was told they did not have that information and I had to go to the store.
I just went to the Apple online store and ordered it. It says shipping in October which I was getting anyways.
In regards to the C, my local stores have them (Radio Shack, Best Buy, and VZ). It may be worth a call to VZ.
