DVD Price War NEW YORK (Associated Press) - Wal-Mart is upping the ante heading into the holiday season, trimming the online preorder prices of some upcoming DVDs following last month's price cut on books.

The move led rivals Amazon.com and Target to reduce the prices of some of their online preorder DVDs, which pushed Wal-Mart Stores Inc. to take a few more cents off its offerings.

The world's biggest retailer said late Thursday that it would lower the online prices of new DVDs such as "Harry Potter and the Half Blood Prince" and "Star Trek" to $10.

But when Amazon reduced some of its DVD prices to $9.99, Wal-Mart shot back by lowering its DVDs to $9.98 as of Friday morning. © Copyright 2009, Associated Press
