I also ordered the ID roller things on 12/1. The morning of the 7th I got an email with the Sorry your order has been delayed message. That same afternoon I got another email saying it had been shipped and a tracking number.
So then I clicked on the tracking number and the message there is "Pre-Shipment Info Sent To USPS. USPS Awaiting Item.
Next I looked at my account where it says Preparing To Ship and delivery expected on the 10th.
Huh?
