just had my own question answered..my card was charged at 2:01PM EST for full amount and Apple Store Order Status switched from Processing to Preparing for Shipment at 3:42PM. So figure around 2 hrs difference between CC charge and prepare for shipment..
Mine hasnt been charged yet, but am Preparing for Shipment now. They seem to be doing it all weird, or banks are reporting it all differently. Most likely the latter
