Answer: SEASONPASS

A season pass typically refers to a ticket or package that grants someone access to multiple events or activities during a specified season. In the context of a "Superfan's purchase," it suggests that a season pass is something that avid fans might buy to attend all or most of a particular series, such as a sports team's games, a concert series, or a theater production. It provides convenience and cost savings compared to buying individual tickets for each event.
