Think about it. Yes, your package is taking longer. It's coming from a truck you don't expect because of all the contracted delivery drivers. You don't know when it's coming.
And neither does anyone else. This would not be the time of year to start searching through packages, particularly to find whatever you ordered.
Think of the current flurry as a mixed blessing. Breathe easy. If the USPS can barely handle your package, I'm pretty sure no other institutions can, either.
We get it. Buy drugs.
