Once you're signed in, head over to your Deliveries and scroll down to the order you want to change. Weekly orders are organized by delivery date, with your past, current, and 3 future orders available to view.
Select the drop-down menu under Delivery Date to switch your desired date for that week. Whatever day of the week you choose will only update for that specific week, not future orders.
To make a permanent change to your subscription, click on the person icon in the top right-hand corner, followed by Settings, and then select a new day from the dropdown box in the Default Delivery Day.
One last thing! The available delivery days we show you are based on where you live. If you don't see a day displayed, it's not available.
