How much of meth cost?

In Australia (as of January 2012), SWIM (Someone Who Isn't Me) pays $100 AUD for "a point" of good quality, high purity meth. In other Words 100 mcg or a tenth of a gram. Am I being ripped off?? SWIM is in Perth and would be particularly interested in hearing from those in the Eastern States. Although SWIM is sorta glad it's not cheaper, or I could see SWIM's recreational use jump to chronic daily use pretty easily if the price was lower.
