UCCU branch by the NW gate. There are always people dumping tickets there and usually far below face and often free if it's after the start of the game or close to kickoff.
Worth a try. Bet you'll get better seats for a fraction of the price of a season ticket and be able to attend most games. I do this with the Jazz games all the time. I always get great seats even within an hour of tip-off and haven't paid face value in years. Might change if we're undefeated late in the season, but that's not likely. Also, the colder the weather the cheaper and more plentiful the tickets.
