NEW YORK (AP) — The National Retail Federation says people have been spending less on holiday shopping than they did last year. The trade group says a record 141 million people likely shopped in stores and online from Thanksgiving Day to Sunday. Last year, 137 million people shopped during the four day stretch. But spending is expected to fall for the first time ever since the group began tracking in 2006. It says over the four days this year, spending fell an estimated 2.9 percent.
