Sendit.com is backordered, even though it says usually available on the page. I placed an order yesterday and they said they would have to order more.

Amazon.co.uk says ships within 4-6 weeks, so that's kind of out for me.

Play is also out of the discs too, btw.

Where else can I get the disc at a good price?

Try Australian sites.

Try Australian sites.
I guess EzyDVD is as good a site as any? That's the only Australian site I've ever ordered from before.

Also try http://www.dvdcrave.com/
They're usually cheaper than EzyDVD :)

EDIT: A useful search site is:

The title was recompressed for the European releases, and some have reported a subtle improvement in picture quality. Though to be fair others have said they see no difference.

I believe there are also a couple of extra bonus features. The cover art is nicer, too.
