During December USPS have experienced bigger delays than perhaps ever before. While all packages are not affected, this does mean that some packages sent as early as November have still not been delivered. The warehouses of USPS are so full that certain packages are stuck for week-long periods without any updates at all, and this is expected to continue until after Christmas. We sincerely apologize to all who are affected, but we are committed to making sure all deliveries will happen in the end, even if heavily delayed. We will continue to monitor the situation closely. 

Message from USPS:

"USPS IS EXPERIENCING UNPRECEDENTED VOLUME INCREASES AND LIMITED EMPLOYEE AVAILABILITY DUE TO THE IMPACTS OF COVID-19. WE APPRECIATE YOUR PATIENCE AND REMAIN COMMITTED TO DELIVERING THE HOLIDAYS TO YOU."
