Harry Potter fans make sure you check this out! The Harry Potter: The Complete Collection Years 1-7 is available for pre-order at Amazon for $48.99 (50% off). This will be released on 11-11-11, but when you pre-order, you guarantee the lowest price between now and release day.
Supposedly, Warner Brothers will be retiring all the Harry Potter movies on 12/29/11, so you’ll want to get them before then. I’m sure they will be released again in the future (like with Disney movies), but who knows when.
