Once an order has been placed with Safeway Grocery Delivery, customers generally cannot directly add items to that specific order. However, they do have the option to place a new order to include any additional items they wish to purchase. It is important to note that the delivery window for the initial order must still be respected, and new orders may be scheduled for a later time depending on availability. Customers should be mindful that changes to an order may require them to review order timing, availability, and potential delivery charges. To ensure they have the most accurate and updated information regarding their orders, customers are encouraged to refer to the current web page for guidance on managing their orders and any related policies.
