Casablanca (Ultimate Collector's Edition) -about £15inc.
I already have the Blu-ray Amaray but I think a faux-leather Casablanca passport holder and luggage tag will look nice when I'm going through the airport
Seriously, this is a beautiful set for fans. Excellent eBayer. They had the HDDVD briefcase Blade Runner and enormous ET: Ultimate Gift Set (beautiful!) for £20inc too.
Actually 5 discs.
They also have The Wizard of Oz Ultimate for about £27inc. You may need to ask them to be 'helpful' with Customs.
The only additional extra on Casablanca (to the normal HDDVD/Blu-ray) is "Jack Warner: The Last Mogul" (57:38)
