Once you’re signed in, click on your name in the top right hand corner, then "Settings." Next to where it says “Promo Code,” click on the "Add" button.
If the code is valid, it’ll show up in your subscription settings next to “Promo Code.” You’ll see the discounted total in your next confirmation email and on your Deliveries once you’re charged. (If there’s an error with the code, we’ll let you know when you try to add it.)
FYI: Some promo codes have usage restrictions depending on your plan or the length of the promo. It’s possible that a promo code could appear to be valid but can’t be applied to your next order. If you ever want to make sure the promo is working on your account, contact us for help.
