So called “junk fees” are becoming more pervasive in Pennsylvania. The fees are surprise charges that don’t appear in initial price advertisements, but often inflate a final purchase cost by hundreds, even thousands of dollars. Pennsylvania Attorney General Michelle Henry told a U.S. Senate panel Wednesday that these kind of added costs damage the competitive marketplace for borrowers, renters, travelers and ticket buyers. She says her office has joined 15 other state attorneys general in calling on the heads of some of America’s biggest banks to eliminate these hidden costs, including overdraft fees and charges assessed for insufficient funds.
