The local Blockbuster (and likely all Blockbuster stores nationwide) is offering an Iron Man bobble head as a 'gift' when you put 10 dollars down on an Iron Man preorder. If you were going to pick this up on the first day of release, you might as well get it at Blockbuster for the extra swag.
Official release date for the DVD is Sept. 30.
(as usual, sorry for the poor cell phone camera quality)
