Delivery date changed, why?

I bought an ipad mini online, few days ago, but when I tracked the order today, the delivey date changed. It should be delivered on Nov 14 by Standard Shipping, as I got from the email. But it change to 19th.

Im a visitor from China, and will leave on 22nd. The shipment address is my friend's.

Is there any way I can get it before I leave? I can pick it up in stores which are near me.

Thanks
