Amazon.com said on Monday it would offer free shipping with no purchase minimum for the first time this holiday season, heating up the competition with Walmart and other rivals vying for customers' Christmas shopping sprees.

The U.S.-only promotion, effective from Nov. 5, waives the $25 minimum that customers outside Amazon's loyalty club Prime must hit for free shipping. The deal lasts until Amazon can no longer promise items in time for Christmas with free delivery, which typically takes five to eight business days.
