Even those have fallen off a cliff from where they would've been years ago. Last year Game 5 settled around $200 get-in-the-door. When I sold my extras in 2018 for the DS series that looked likely to be Cubs at that point, but ended up being the Rockies, I got much, much more than that for a non-elimination game.
There is still demand, yeah. Any of the playoff games are sell outs or close to it. But they have things working against them. The times are never very good, for one, and the demand just isn't what it used to be. There's a large contingent of people who just aren't in the market until it's a clinch game for the pennant or the World Series that everyone is starving for. The DS just doesn't excite people on the fringes anymore. 20 years ago it was a hot ticket, even 10. But do this every year and it's not that exciting anymore.
