Ffs. Wtf? What good to me is tracking the item AFTER I receive it? Fucks sake. Next day delivery my ass.
You can only track it if it has been sent Special Delivery - and only when it's sent VIA Special Delivery is it guaranteed to be delivered the next day. If it was sent 1st Class Recorded it's guaranteed to be delivered between 1-2 working days and the tracking number is for the person who sent it so that they know you've recieved the item. Simples. ^_^
