Considering how common (and small) these items are, it doesn't make much sense to me that only one vial is stocked on the entire shelf of a medical supply store. More elusive/expensive medication could still be drip fed out in the current system, but all of the common stuff I feel is far too rare/hard to find at the moment.
This issue makes it very hard for a physician to do to their job and oftens ends in a PC who can perform the task IC scraping the the patient off with a @puppet-request to the resident NPC.
Thoughts?
