If you don't get a FourSquare special when you checkin, ask the store clerks if there is one--last time I got 40% off a $50 purchase by asking about it when no special showed up upon check-in.
Official Sacramento Kings Team Store.
NOTE: On Kings home game days, Kings Team Store closes ½ hour before doors reopen for game (usually 5:30pm for 7pm game). Store open inside building only duration of Kings game.
