"You know what would really be great, and would almost certainly save money? If prescriptions could be done electronically."

This can be done today, and frequently is (depending on the organization). Schedule II is a bit nastier since there are regulations about electronic delivery, but the vast majority of medications can be sent electronically in exactly the manner you describe. Just two weeks ago I was in for a follow-up and they ordered some meds that were automatically sent to the pharmacy, where I simply picked them up. Easy.
