That happened to me in 2008 when OU played Florida. My buddy and I made the trip to South Beach without tickets and spend 800 each on tickets from a guy there that ended up being counterfeit. Major bummer.Just a warning...not that you haven't heard this...but be careful about buying tickets from just anybody.
Last January in NOLA on the day after THE GAME I bumped into some folks I know and in our catching up they told me how they bought tickets two tickets off the street before the game. They paid $1700 for the pair and when they got to the gate their tickets didn't scan and were deemed "counterfeit." I asked them what they did and they said they went back to the hotel and watched it on TV.
