Was in my local Borders yesterday (Lambton Quay) and my daughter pointed out a bunch of cheap HD-DVD's for $9.99. Obviously the selection is limited but there was
Bunch of Harry Potter movies
40 Year Old Virgin
Leaving Las Vegas
Other stores might have different selections/availability.
For $9.99 thought it was a great deal since I do have a HD-DVD player (of course) and while I also have a PS3, I am not retiring my player any time soon
