I mail order my recurring prescription medicines from the hospital pharmacy all the time. No waiting in line and they give me a substantial discount.

What exactly do you mean here?

That you don't feel safe receiving your medicine being delivered last mile from some random UPS guy?

If this is what you mean -- I get my medicine by mail order from CVS. I cannot imagine now having to go to CVS every single month I get my medicine.

In many cases, insurance mandates that you use their contracted mail-order pharmacy when possible. In other cases, they recommend but don't require it since the fees are lower for everyone that way. This is in the USA.

For pills, I would expect they'll use USPS, not UPS. That's how I get my medicine. It comes in a shipping bag instead of a box or rigid envelope.

My partner buys legal drugs from her pharmacy. Half the friggin time, there's some supply problem on the back-end, and she can't get her drugs in time.

Anyone who could fix this problem will get her business in a heartbeat.
