So I've just ordered an iMac and a Retina MBP. The order is currently in the stage of "Preparing for Dispatch" and both are showing as "Dispatched: Within 24 hours" however are showing different delivery dates. Neither machine has been customised. The iMac is showing as estimated to be delivered 6th Nov and the rMBP on the 11th. Is there a particular reason for this? The obvious is that they're coming from different locations, or are they more likely to correct upon actual dispatch & arrive together?
