For domestic orders: If your tracking number shows the item was delivered and you haven't received it, please contact USPS and reference your tracking number. USPS will provide you the details of the location of your package.
For international orders: If you selected USPS at checkout, please note that USPS First Class International and Priority Mail do not provide visibility or tracking of a package’s location once it leaves the USA, and USPS will not be able to account for it. International customers must contact their local postal service for delivery information. It will be up to the local postal service of the destination area to deliver the package.
