Start to Thinking that Apple wants to troll us. Its preparing to ship since almost a week. Tomorrow it should be Here and its STILL preparing-.-
That's because your shipping label was probably printed and put on the package about a week ago in China. Apple then bulk ships them to Europe because it's cheaper and hands them over to DHL/UPS 12-24 hrs before the delivery. Because DHL/UPS Express is really fast in Europe.
They don't show you the shipping info in advance so that you don't panic because you don't see any progress on the shipment for a week.
For reference I checked my mails: I got the shipping mail for my 6s at 6:34 pm and it was delivered 9 am the next day.
