Target Corp (TGT.N) said it will drop shipping fees for all online orders during the holiday shopping season for a second year in a row, ratcheting up competition with rivals including Wal-Mart Stores Inc (WMT.N) and Amazon.com (AMZN.O). The discount retailer also said it has struck a deal with Borderfree Inc to ship products to 200 countries and territories outside the U.S. during the holiday season. “Traffic is very important for us during the holidays and … free shipping was very well received last year,” Chief Executive Officer Brian Cornell said on Thursday.
