The best way to change your delivery instructions is to edit them during your next checkout. You'll be given the option to edit your delivery information under the Delivery Address section on the review page before you complete checkout.
On goodeggs.com, you'll want to click on the Change button next to the Delivery Address header to update your delivery instructions. In the Good Eggs iOS app, you can go ahead and click directly on your old delivery instructions and edit from there.
If it is past your order cutoff and you don't have the option to edit your delivery instructions yourself you can reach out to our Community Care team for assistance.
