It has generally been shown that the virus does not last long on packages and there is little risk from transmission through the mail. However, I believe in giving information and letting people decide their own level of risk.
Our county is currently running at 0.55% infection rate and while it has risen a little, it is relatively stable at a low level.
So far, we are well, however 2 people in our household work in public government jobs (teacher and library clerk). One is fully vaccinated, the other has had the first in the series. I have also had my first.
For shipping, I am washing my hands well and putting on a mask. Stock is kept in plastic bins in my studio, which is a separate room in the house, and only used by me.
USPS does continue to be affected, and it is very arbitrary. Tracking is emailed to you with all regular packages, I have tracking upon request for Tiger Club packages.
