The Movie Stop I went too had the same $29.99 price. That is the price that Movie Stop uses for all the combo disc, everything else is $24.99 or less and, most WB (that aren't a combo) are $19.99. They had Clerks 2 for $19.99 (which I picked up, best comedy of the year) and Scooby Doo for $18.99. I thought it might have been priced wrong so, I had the clerk check the price in there computer and $29.99 was the only price they had. Since Poseidon was originally announced as a combo, I think someone forgot to update Movie Stop's computers once it became an HD DVD only release. I thought the movie was enjoyable but nothing great, Emmy Rossum with her low cut shirt helped! With TrueHD 5.1 I would have gladly picked it up for $19.99 but, not at $30.
