Even here in cali with all the medi buds around, it's still quite common too see O's for $500-$600 for the really bomb stuff. I know this sounds insane for the "rest of you", but here in the Bay Area, that is not really out of line assuming you are getting some of the top-end medical grade stuff. This is also the same in LA, NY, and other "pricier" markets. In fact, everything in the Bay Area is pretty expensive, whether it's housing, taxes, or even gas which is currently around $4 /gallon here at many stations.
