# Catalogs

Catalogs are a key component of LootLocker’s Economy system, allowing you to assign prices to items for sale within your game through [Virtual Purchases](https://docs.lootlocker.com/commerce/virtual-purchases) or [Real Money Purchases](https://docs.lootlocker.com/commerce/real-money-purchases). Catalogs support the sale of items that can also be distributed through Progressions, Triggers and Leaderboard rewards, including Assets, Progression Points, Progression Resets, and Virtual Currency. Catalogs are essential when integrating your in-game store with a platform’s payment system, such as the App Store or Steam.

You can create as many Catalogs as your game needs, whether a single catalog for your entire store or multiple catalogs for different categories. Each item listed within a catalog is referred to as a catalog listing. Listings can include single items or bundles, support custom metadata, and store the item’s price along with other relevant information for in-game transactions.
