USPS shipping can be a little weird sometimes. Sometimes the package doesn't get scanned properly when it's picked up by the Post Office. Unfortunately, this happens more than we would like. The good thing is though, USPS picks up packages every day at our facility and unless your package was packed after they picked up, it is in transit with USPS. Give it some time for the site to update. Also, it may not update till you actually receive the package. I've had this happen to me plenty of times. Just keep an eye out as you should be receiving your package soon!
