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.
The plan can be changed right from the Deliveries page or in the Cart by selecting a new plan size under "Meal Plan".
To make a permanent change to your subscription, head over to your Settings and click "Change" next to Weekly Default Plan. This will update all future weeks that haven't already been charged.
One last thing! When you increase your meal plan or select a smaller plan, we'll automatically add or remove meals on your existing menu. So double-check your orders after making a change!
