Any prepaid orders that didn't ship yesterday will ship today.
Order #5 here...still no word on my order. Was your invoice a reauthorization of your payment? Or a notification from Schiit that your order is processing?
My payment was from early on when PayPal immediately disbursed funds, so I wouldn't expect a reauthorization notice. However, if you received some other notification from Schiit that you order is now processing, then I would be concerned that Schiit is processing orders out of sequence.
