USPS: Due to increased volume on USPS' delivery network, we have found on occasion orders will be marked delivered before they're actually delivered. While we firmly disagree with this unofficial practice by the USPS, we do need to account for that possibility. We're happy to offer a replacement free of charge, but, orders marked delivered must wait 7 business days from the date it was marked as delivered before a replacement can be shipped.
FedEx: No wait period required.
