Shoppers pass a giant Christmas tree display beside an outdoor ice rink outside the GUM luxury department store on Red Square in Moscow, Russia, on Monday, Dec. 22, 2014. The ruble's rout, sparked by falling oil prices and sanctions imposed on businesses including OAO Sberbank, prompted Russians to begin buying luxury goods from Porsche sports cars to Tiffany rings to preserve the value of their savings.
