Eagles fans are driving Super Bowl ticket prices to all time highs. StubHub, the internet ticket broker, says that despite the New England Patriots being in the Super Bowl again, and frigid temperatures in Minneapolis, this year's Super Bowl is on track to be the most expensive in history. ‘The cheapest ticket price available on StubHub right now is going for around 3,200 dollars to get into the door. The most expensive ticket price that we've sold so far for $22,000, said Cameron Papp of StubHub. Papp says that the NFL's efforts to expand the game outside of the United States seems to be working. He said people from 18 different countries have purchased tickets to the Super Bowl. "NFL has made a strong investment and you know Mexico, Europe and even up north in Canada. So this is one of those events that a lot of people just traveled to, and I'd say outside of maybe the World Cup the most popular sporting event that we have in the world,’ said Papp.
