I agree that since they had just released Season 2 of Grey's Anatomy, they should have at least put out a few copies of season 1 for those latecomers...
The new 450 price point really makes impulse purchases much more 'impulse', if there's such a thing.
Even though you might find it at 299 elsewhere, the time, fuel, and effort involved sometimes add up to more than the difference.
But they should also start releasing newer films. While they do have a few new release this month (Grudge 2, Guardian, etc.), a lot of the really great one are still awaiting release including Little Miss Sunshine and The Illusionist.
