Santa made some early stops across the country this week. But instead of sliding down chimneys, he quietly walked through Walmart's automatic doors. Anonymous do-gooders paid off layaway tabs at Walmart and Toys R Us stores in New Jersey, Pennsylvania, and Arizona this week. The benefactors at Walmarts in Pennsylvania and New Jersey, described by NBC New York as "Secret Santas," each picked up bills totaling $40,000 or more.
