Payment has also been taken from my account (it actually shows it came out yesterday), and I got a mail from Quidco this morning saying my order had started tracking with them for my cashback, which is nice as I'd forgotten I'd gone through Quidco😀
I've still not got a TNT tracking number, and my Apple Shipment Status is showing two different dates, estimated delivery date is the 12th, but current delivery status (In Transit to Customer - Shipment on Schedule) has the 4th. I guess that the re-furb AirPort Express I ordered has confused TNT, I'm a bit more hopeful for a Monday delivery now though.
