If you've received notification that your package has been delivered, yet is not in your mailbox, you might be thinking, "What the heck USPS!"
The USPS tracking system and notifications are set up so that, at times, the USPS will mark a package as 'delivered' according to it's estimated arrival date vs. the actual delivery of the package.
With this in mind, if the USPS says your package has been delivered, yet it's not in your mailbox, this is an idiosyncrasy in their system, and the package will most likely show up the following day. Keep an eye out for your package and let us know if it does not arrive by the end of the following business day.

PLEASE NOTE: The occurrence of these delays and inconsistencies in delivery are typically heightened around national holidays and any high volume mail periods.
