I just spoke with BBFB. The CSR was very helpful. He showed a BB PO that has been fully paid and BB is getting approx. 1200-1400 units delivered to their warehouses tomorrow. Orders placed from bestbuy.com will be shipped from your closest warehouse only. Orders placed on bestbuybusiness.com will be shipped from ANY warehouse.
He guessed (yes, I said guessed) that if the warehouses have them tomorrow, they will start actual shipping to customers on Monday. This means I'm looking at Wed or Thu for delivery.
He also said that the B&M stores are not likely to get more than a few units (3-5) per store.
It sounded to me like the actual delivery dates will be BBB.com customers, then BB.com customers and finally B&M customers.
Hope this helps...
