IMO (and this could be wildly incorrect) the market in perth seems to be dominated by two groups (perthites probably know who i'm talking about).
Yeah, or get everyone you know to refuse to pay the higher price and quit drugs until you get a better deal... the dealers will not reduce the price voluntarily - they will need to be coerced into it by crap sales.i think you'll just have to grin and bear it and accept that the prices are so high because there are fewer competitors.
