The pharmacy in question is CVS Specialty, and they already offer shipping direct to a local pharmacy.
That doesn’t really change the calculus that if it is sent via USPS, and USPS has slowdowns, that it may take dangerously too long to arrive.
They don’t really let you choose what partner they’re going to ship with, so it’s a “you get what you get” situation and I can’t ask for FedEx specifically if I wanted it. They ship with whatever’s cheapest to them at a given time.
