Forgotten Tales

It's available at the bank if you want to spend some money. I'd like some additional storage at the inn as well.

It's safer in there. Always a good thing.

Buying any additional storage applies to all locations that have storage. In other words, if you spend the ~$6 US, you get 20 extra slots (1 screen) at the bank AND the inn, plus it will apply to any future storage locations. Purchased extra storage still does not apply to houses

Fantastic! Strange though...it says

Bank 20 extra storage

Not

Bank and inn 40 extra storage

In 'buy extra stuff' menu.

From the Game Help:

9.6 Bank Expansion
Each character can have access to 20 slots of space storages (directly or thanks to certain quests solving), such as at the Bank in map -1.1. Buy and activate a Bank Expansion to gain 20 more slots, forever, [font=]in each of the storages[/font] (private houses not included). You can activate as many Bank Expansions as you want.

Good spot. I'd not read that.

Thanks for clarifying.
