## What is a SKU list?

[SKU lists](/core-api-reference/sku_lists.md) are used to group many SKUs into a collection that can be filtered and exposed to customers in the presentation layer. You can create a SKU list by selecting and sorting items from the available SKUs manually, or by using a regular expression to populate and sort them automatically.

SKU lists let you:

* Filter, display, or apply rules to a selected set of SKUs, including their prices and availability.
* Enable and manage promotions for a set of SKUs.
* Restrict the scope of a promotion to a set of SKUs.
* Group SKUs into a bundle assigned to a market with a special price.
