To update your default address, head on over to the Account Settings Page. 🏡
From there, you'll want to click "Edit" under "Shipping Address":
Your address information will expand, and allow you to make changes to name, address, state, zipcode, and phone number. Sorry- no PO Boxes. 📬
Scroll down to the bottom of your address book and find the + Add Shipping Address button.
You can then click the Save & Use button to change your default address - and don't forget to leave a brief note for the delivery carrier about where to leave your box!
Alternatively, to quickly change your default address, find the pencil icon ✏️ on the My Orders page.
