What is operated under contract with retail partners to provide postal products?

The correct choice refers to a Consumer Pricing Unit (CPU) because it specifically operates under contract with retail partners to offer postal products. This arrangement helps expand the reach of postal services through partnerships with various retail outlets, enabling customers to access postal services in convenient locations outside traditional post offices.

This integration with retail partners allows for wider distribution and availability of postal products, making it easier for consumers to access necessary postal services without needing to travel to a dedicated post office. The collaboration with retail partners helps enhance customer convenience and streamline the process of obtaining postal services and products.

In contrast, while a Post Office is a point of service for postal needs, it operates as a standalone entity rather than through retail partnerships. An Integrated Delivery Network refers to a system designed for managing deliveries more effectively and does not specifically relate to retail partnerships for providing postal products. A Parcel Drop Center typically serves as a location for dropping off packages but does not specifically involve contracts with retail partners to provide postal services.
