In 89 I sold one Standing Room Only seat to the 2nd game of the playoffs for $200 minutes before the game, which fully paid for that ticket and the other three I bought from the Cub's phone in ticket sales (one for me, one for my dad, and one for his uncle who took me to my 3rd Cub game, the game after Holtzman's 1969 no-hitter). Adjust for inflation, the fact that a 9th row box is a wildly better seat than an SRO ticket, and the fact that the ticket this year is to a game the Cubs have a much better chance of winning, and $550 is not a bad deal.
