Update - July 15: Details shared with GamesRadar+ clarify that Fan-tier subscribers will still be able to "browse" the Crunchyroll store, while only Mega and Ultimate-tier subscribers will have access to the "new curated experience" coming in the August store update.
I've asked for further clarification regarding Fan and non-subscriber shopping access, the scope of this new exclusive section, and how the Crunchyroll store's inventory may change following this August update and the ongoing "final sale" of many items.
