A product bundle is a group of two or more separate products, services, or in-game items sold together as a single package, typically at a combined price lower than the total cost of buying each item individually. In digital commerce and game backend platforms such as Namazu Elements, a bundle defines the collection of items, currencies, or entitlements a player receives, while one or more associated SKUs represent the specific purchasable listings and platform-specific pricing (for example, on the Apple App Store or Google Play) through which that bundle is sold.
