As an escalator whisked Marlene Dreher toward Nordstrom's third floor, she flung out her arm and cried "Focus, girls, focus!" Her two daughters and a daughter-in-law – momentarily sidetracked by a display of dress boots a floor below – fell into step. The women, all Canadians, were on a carefully scripted shopping trip to Spokane. In four days, they planned to hit up to 100 stores. It fell to Dreher, a twinkly-eyed grandma, to get the troops to their first agreed upon stop: Nordstrom's children's department.
