No Estimates For Shipping Method Reason: One or more of the items in the order does not qualify for Shipping Method
Explanation: Certain shipping methods are only valid for certain products. The classic example is USPS Media Mail, which only accepts books and recorded media (and a few others).
Remediation Steps
If your product is showing as not qualifying for a restricted shipping method and it should qualify, you need to mark the item as a special type.
Navigate to:
Select the item you're troubleshooting.
Click on the Shipping tab for the selected item.
Scroll down a long ways to the 'Shipping Method Specific Options' page, and change the flags as needed to allow this item to use this shipping method.
