Me and a friend are going to buy tickets for game three of the NBA finals. I've never bought tickets for an event like this so before I spend 750 or so I want to make sure I'm buying legit tickets. Is there a way to guarantee that you're not getting screwed by counter fit tickets? I had a friend at the gym yesterday say that he had hard tickets to a game and when he went to go in they said the ticket had already been scanned and he didn't get in.
