Overpriced? I disagree. Maybe the street drugs are, but the benzo's (Xanax, Valium) are about the same as I was paying from a "street pharmacist" that was giving me deals cuz he's been a friend of mine since before he started selling 'em...
That reminds me, medical supplies in the US are overpriced and corrupt. id bet you paid lower than you would at a real "pharmacy" and your friend probably still made a little profit.
