The problem with Australia Post pricing policies is that parcels jump from 500 grams to 3 kilograms , there is no 1 kilo or 2 kilo bags and no sliding scales , if Australia postage had an increasing scale of prices for parcel worked out on a one gram basis then a 502 gram parcel should only cost a few cents extra over a 500 gram parcel instead the cost is almost double . If you went into a fruit shop to buy some apples in a bag at $2 for  500grams and the assistant said '' that because the apples weighed 502 grams you had to pay twice the price '' most people would think that was unfair .

great post appletreeaaa, and spot on, It really irks me having to charge or pay for 3kg. when the parcel is 600gm or so
