Target Corp.'s pledge to match prices of select online rivals this past holiday season is now a year-round promise.

The nation's second largest discounter behind Wal-Mart Stores Inc. is announcing Tuesday that it will now be matching prices that customers find on identical products at top online retailers, all the time. The online list includes Amazon.com as well as the websites of Wal-Mart, Best Buy, Toys R Us and Babies R Us.

Target is also making permanent its holiday offer of matching prices of items found at its stores with those on its website. And for the first time it will include products that are out of stock on Target.com.

The moves follow a disappointing holiday shopping season for the Minneapolis-based retailer, hurt by stiffer competition from online rivals.
