Amazon now lets Prime members add items to completed orders

"Amazon has announced a new shopping feature for US Prime members called Add to Delivery that lets you add additional items to completed orders that have yet to be delivered, instead of having to create an entirely new order. The feature is only available on Amazon's app and on Amazon.com when accessed on mobile devices, and is limited to eligible items that include electronics, clothing, books, and grocery items."

"Figuring out what items are eligible seems simple enough. If the item you're viewing can be added to deliveries arriving later in the day or tomorrow, you'll see a new blue Add to delivery button below Amazon's standard yellow Add to cart button. Tapping the button instantly adds the item to your upcoming delivery, but if you press it accidentally, or quickly change your mind, an undo option will immediately remove the item from the order."

A new Add to Delivery feature allows US Prime members to add eligible items to completed orders that have not yet been delivered, eliminating the need to create a separate order. The feature is available only on Amazon's app and on Amazon.com when accessed on mobile devices. Eligible categories include electronics, clothing, books, and grocery items. The feature was tested with some Prime members and is now seeing broader rollout. A blue Add to delivery button appears below the Add to cart button for eligible items, and an undo option removes accidentally added items. Added items do not incur extra shipping fees, though Prime requires a paid membership.
