Hey, not sure about SA, but I pay ( when I cant get my own) Between $65 and $90 a metre, split. Quantities is hard, cos it depends on how much you use it. We run 2 coonara's ( one in shed), when I'm home I have fire redhot the whole time ( Im coldblooded)
And we go thru about I dunno, maybe 9-10 metres a winter. We also get offcuts from the local sawmill for next to nothing.
Hope this helps..
