Kathi Nygaard left her home in Potlatch, Idaho, with a carefully scripted Christmas shopping list: Pots, pans and a Magic Bullet blender for her 20-year-old son, who’s getting ready to leave home. Boots, slippers and shirts for her daughter. Barbie dolls for her two great-nieces … But during 12 hours of marathon shopping on Friday, including stops in Pullman and Coeur d’Alene, Nygaard also threw a few extra items into her cart. She bought a $248 laptop computer at Wal-Mart and an electric roaster at Shopko, which she thinks cost about $40.
