USPS is the most economical and reliable shipping option, but occasional hiccups happen. Once USPS picks up a package from us and issues a tracking number, the USPS is responsible for delivery. If an item does not arrive, is missing or late in arrival, possibly stolen, or damaged in shipment, the buyer must contact USPS directly with the tracking number and ask for a Case Number to be assigned. (NOTE: Once a case number is assigned, we have found that in most cases, the USPS locates the missing article.) We will try to help in whatever way we can, but the USPS must confirm the status of an article with a Case Number before we can take further action. Contact the USPS at USPS.com (you can also submit a Search Request after 7 days).
