Amazon Blocking Warner Movies Pre-Orders in Latest Feud

Amazon.com isn’t accepting pre-orders for Warner Bros movies on its website, the latest of the online retailer’s contract feuds to spill into public view. Customers trying to pre-order films such as “The Lego Movie,” “300: Rise of an Empire” and “Winter’s Tale” are instead asked to sign up to be notified when the item becomes available.

Digital downloads of the movies are available for purchase through Amazon Instant Video. The world’s biggest online retailer is seeking concessions from Warner Bros that would give it more of a margin on sales of DVDs and digital versions of its movies, said a person familiar with the matter, who asked not to be identified because the negotiations are private.
