A lot of prescriptions are filled by computer now. I REALLY dont think pharmacies keep two stashes of meds depending on who your insurance is. And then the source of your insurance could be the govt assistance or not, for the same insurance. People would be dropping like flies if we were getting bad meds, and they would probably start with heart meds (and yes ive worried about getting bad generic drugs. But hey we are sui half the time anyway, so should we complain??).
