Looking to build the small retaining wall for which bricklayer has asked us to get a half tonne of sand and 5 bags of cement. I cannot carry it in my car so I tried to rind couple of places nearby and also bunnings none of them do shipping for this quantity. Most of them do shipping for min 1 tonne of sand which is way above my requirement. Any places from where I can get this 0.5 tonne sand delivered at home (in Sydney)? How much this will cost appro?
