You can change an address or delivery window (if you have more than one delivery window option in your area) for a single delivery by logging into your account and heading to the "Upcoming Deliveries" page here.
Click "Change" next to the delivery day you want to modify (if it's grayed out then it's past the deadline to do this) and enter in the new address and delivery instructions/window/settings. Save the changes for that delivery day only, and then you're all set. This is also where you'd change the delivery window (if multiple options available) if you need to adjust when you'll be able to receive the delivery.
You have until 9am PST two days prior to the delivery day to make this change.
If you would like us to verify that it went through successfully please fill out our contact form at thistle.co/contact for any further questions you may have.
