Many hundreds of packages are delivered to our warehouse each day. Depending on the time of year, after a package arrives at the warehouse it can take up to 1-2 business days to appear in your account (Monday-Friday in the United States, excluding U.S. Holidays). If your package does not appear in your account after 2 business days, then there is a possibility we were not able to process your package.
If you believe this is the case, please email our support team at support@postfromus.com providing the tracking number and any other additional information about your package to assist our investigation.
