But that's almost a full mile from the stadium. I assume most, if not all, stadiums have that kind of option if you're willing to walk far enough. If we're talking exclusively the "official stadium parking" immediately around the stadium itself, $25 is as good as you're going to get in any NFL venue.
(Just checked and even Jacksonville charges $25 per game)
