Brian,
In preparation for faxing directly. I faxed a couple of scripts that had my "electronic signature" only on them (non scheduled drugs) and we immediately received calls back from the pharmacists saying that they had to be signed. Although this may just be an educational opportunity for the pharmacists, it did give me a chance to reflect on your final comment. I agree that the physical exchange of the typed Rx to the patient has its advantages; not the least of which would be for them to consider where they want to have their script filled.
Currently, I am prescribing over half of my meds off of the Wal-Mart, Target $4 list ($3 for Price Cutter).
