Amazon has tons of DVDs and Blu-rays onsale all this week, starting today.  There are some narrow windows for quite a few of the deals, but the prices are being announced the night before the sale price starts, so you don't have to check back constantly.  Listed below are the highlights.  Note: Times listed are Pacific Standard Time.  I'll try to update the list with prices as they're announced.  Deals can be accessed from: here.

Anyone have any feedback on The Mummy: Tomb of the Dragon Emperor?  I enjoyed the first 2 Mummy movies, and even the Scorpion King (but not as much).  I'm thinking at $2 for a blind-buy, might be worth it.

IMO even worse than "The Scorpion King" as it has the same characters as the first two but a story far, far away from anything the first two represented and even more "sandy" than the two "stingy king" features.

For $ 2,00 surely ok for collection purposes, but with regards to viewing pleasures I'd steer clear

I actually enjoyed it. Of course like others have been saying, it's not as good as the first two, but sequels usually aren't by the third one. Now the Scorpion King that was a horrible movie. Saw it in theatres when it came out and that was the last time.

Prices for Turkey Day have been added!

Harry Potter is actually marked down already to match Wal-Mart (the first five movie are all $10, in fact). I probably would have bitten on these if they hadn't just announced ultimate editions.

Oh boy, I just got back from Wal-Mart.

They were out of The Mummy movie, Hellboy II, G.I. Joe, Star Trek, 17 Again, Year One.
In fact they were fairly picked over.

I managed to snag a few deals.
$2 each
Blazing Saddles
Underworld
Underworld Evolution
The Marine: Unrated

$5 each
Surf's Up
Paul Blart Mall Cop

$9
Aliens in the Attic

They also had Gran Tarino for $5, but it was the Full Screen edition, so I passed.

It was a complete madhouse. I waited in the checkout line for 1 hour.

Last year wasn't too bad, but this year it was much, much more crowded. Never again. I don't even care if they have DVDs for $1, it's just not worth it.
