Once you’re signed in, head over to your Deliveries and scroll down to the order you want to edit. (Weekly orders are organized by delivery date, showing your past order, current weekly order, and up to 3 orders in the future.)
Select “Change Details” under the order you want to edit, and click on the "Change" link next to that week’s delivery date. You can select a new delivery date for that week on the calendar, and edit any of the upcoming weeks shown. Whatever day of the week you choose will only update for the weeks chosen not for all future orders.
To make a permanent change to your subscription, you can click on the default delivery day listed above the calendar then choose the day of the week you’d like your deliveries. This will update all weeks currently showing on the calendar as well.
One other thing to note: the available delivery days we show you are based on where you’re located. So if you don't see a day displayed, it’s not available.
