In this digital age I would be very leery of ticket scalper....back during super bowl 34 and 36 we didn't have to worry about this scam that people are using these days.
Some people have hard copy tickets, but once they download them to their phones as a digital ticket, it automatically voids the hard copies...some people are then selling those worthless hard copies to people outside the stadium.
I would stick to legit sites like stubhub, vivid seats, ticket master etc...
Good luck and enjoy the trip..... even if you get priced out it will still be a great atmosphere and plenty of cool places to watch the game on TV I'm sure.
