I had sold out my bleacher seats at $7, so I bumped it up to $8.
Sold it out at $8, so I bumped it up to $9.
Since then, it's dropped off from 3000-5000.
Dropped bleachers to $8, but still not close to selling all. It's hard to tell if fans reacted badly to the price change or there is something screwy going on. Of course playoff games usually pack the house, but since you split the gate it doesn't matter as much.
