I have worked for many companies in my lifespan. We never had Saturday delivery. We didn't mail things out, and things didn't come in. We survived, we made a profit.

If my meds run out during a snowstorm, or I lose them on vacation, or they get disposed of by accident- somehow I manage. I can't call a doctor's office on a Saturday afternoon, and expect to get seen and medicated by Sunday morning. The system will re-work to make it work out. Meds will be mailed out earlier, to accommodate the schedules.

No mail on Saturdays is such a non-issue. People will deal. All this talk about who mismanaged what, when and for what reason has nothing to do with non-Saturday delivery. The post office needs to be like every other place, and cut costs- no matter what the reason for the cost cutting measures.
