For skips you usually have to distinguish between whether you are dumping hard-fill (eg concrete, bricks etc) or general household refuse and green waste. For a price comparison, if you were to take loads of material to the dump yourself, for sorted waste you would probably pay $45-75 per m3, whereas for mixed (non-hazardous) waste prices are usually in the range $130-190 per m3. So skips get more economical as sizes increase.
