What are you trying to accomplish? Are you wanting to know if an inbound package is heading your way so you can track it, or are you just wanting to know if you have been billed for an incoming package? If you are wanting the info so you can track it, then there are a few tools that you can use, but they have to be set up before the package ships. If you are looking to see your up-to-the-minute account status, then no.
We do have a way for you to download a copy of your bill on Monday for the previous week, but I doubt that this is what you are looking for..
