Additionally, it's not even free. Wal-Mart wants to make you pay twice for your movie:
With the purchase of the "Superman Returns" physical DVD, Wal-Mart said customers can also choose from three video download format options -- $1.97 for portable devices, $2.97 for PCs/laptops, and $3.97 for both portable players and PC/laptops.
According to Wal-Mart, the Superman Returns physical DVD will come with a video download "feature sticker" on the cover. Customers will then have to log on to walmart.com/superman, enter the promotional code, and select their desired download format.
Once users create an account and install the video download manager, the purchase completes and the movie download process begins. Wal-Mart said customers can also begin watching the movie while it downloads.
