The Toy Store is a feature in Disney INFINITY.
In the first game, there are six different Toy Stores, one for each playset. Each Toy Store has different items from the other ones, and currency collected in one playset does not carry over. Some items in the Toy Store are required to progress in the story or complete quests, while others have very little impact on the playset.
Disney INFINITY: 2.0 Edition
In the sequel, the Toy Vault is replaced by a giant Toy Store. Nearly every item can be purchased from this Toy Store, with the exception of items from 2.0 playsets, items unlocked by 2.0 figures, and a few other select items.
