If you need to cancel postage that you have already paid for through the site, follow these steps to receive your refund:
- Navigate to the My Labels page.
- Then, from the Shipping Label panel, click the "Cancel/Refund" link.
Note that a refund will not be given if either:
- It’s been more than 35 days since you purchased the postage. Shipping labels will be automatically canceled after 35 days of no use.
- The label was scanned by USPS for delivery.
