NEW YORK — Shoppers were out before dawn in the U.S. for fun and for deals, as retailers that have had a tough year were hoping to bring customers to their stores and websites for Black Friday, one of the biggest shopping days of the year.Black Friday has morphed from a single day when people got up early to score doorbusters into a whole season of deals, so shoppers may feel less need to be out. Some love the excitement, even if they've already done some of their shopping online.Friends Yeshica Jeffers and Stacey Rhodes-Sofer hit a Walmart in suburban Albany, New York, early Friday."We always do it. It's a tradition," said Jeffers, the mother of four children, including twin 7-year-old girls.
