I'm a bit confused... the Track Order button links me to a delivery status from Apple that has been displaying a delivery date of 22 Jan since the first message appeared. Expeditors show the iMac as 'out for delivery' today but they have a 'Requested delivery date' of the 19th. I appear to have no way of getting to any tracking info relating to a specific courier as I've no idea who is delivery (impressive that Expeditors seem to know!) and I've had no texts warning of an impending delivery.
I'm in the same boat. Not sure where it's "out for delivery" to? I'm thinking it might mean it's being delivered to a distribution centre somewhere, and will then be sent onward from there via UPS or such like? At that point we'll get the apple texts and it will also be near the expected date
