# Products

A product (a stock keeping unit or SKU) is a sellable item or service. Products in your Digital River catalog contain all the required attributes to complete an end-consumer transaction (payments, tax, and fulfillment). You can generally configure the product in one of the following ways:

* An [individual product](/commerce-api/general-resources/global-commerce/products/individual-products.md) (single sellable SKU)
* A [base product with variants](/commerce-api/general-resources/global-commerce/products/base-product-with-variations.md) (base product with multiple sellable SKU variants)
* A [product combination](/commerce-api/general-resources/global-commerce/products/product-combination.md) (combination of two or more product components into a single product)

You can retrieve your catalog product information, including applicable discounted prices, by leveraging the available product endpoints. See [Products](/commerce-api/shopper-apis/product-discovery/products.md) and [Retrieving products (synchronous API)](/commerce-api/admin-apis/product-management/retrieve-products-synchronous-api.md) for more details.
