I've ordered an iMac from the UK Online store, but the order tracking isn't too clear. On entering the order confirmation screen it claims all 4 items (an iMac, printer, airport card and iPod) were shipped on September 28th - the iMac via Merge in Transport and the rest by UPS. Next to the iMac it says estimated delivery by Oct 12. There's a tracking number next to the UPS items which when clicked gives another page which says estimated delivery October 9th. The tracking number is in the format of a UPS number, but gives no result on the UPS website. The basic question is what is the significance of the two dates - should it be here tomorrow, or is tomorrow when the order 'merges' and then it's here for Thursday, or something else? Thanks in advance.
