BERLIN, GERMANY - APRIL 03: A woman watches the total price of her fuel purchase rise as she fills her car at a gas pump at a Total gas station on April 3, 2012 in Berlin, Germany. The Bundesrat, one of the five constitutional bodies in Germany, is debating changes to the ways in which gasoline is priced at the country's gas stations, testing various models that will restrict price changes to one per day where the fuel is for sale. Currently the amount to be paid at individual gas stations is often adjusted several times per day. (Photo by Adam Berry/Getty Images)
