Apple is now offering same-day delivery of certain products in its Apple Store app, through a partnership with Postmates. In the San Francisco Bay Area, the Apple Store app is offering a same day delivery option on products that are available in local Apple Stores.

For example, ordering an Apple TV in the San Francisco Bay Area results in a four-hour same-day delivery window, as does an order for a Lightning cable. In some areas, like San Francisco, delivery turnaround times are as fast as an hour, but for some products, delivery times can take up to a day.

In the example, that Apple TV will be delivered within 4 hours for a fee of $19, as opposed to free 2-day delivery.
