As a seller I cannot offer free postage only Australia Post can offer free postage.

I sell and item for $10 and charge $10 postage, in the future I will sell an item for $20 with free postage.

Therefore no free postage.

I sell an item for $10 and take the item to the POst Office and instead of charging me $10 they tell me I don't need to pay to send the item then that is free postage.

Please let sellers state that postage is included in the price of the item.

Also how does the so called free postage work with sending cubed items to WA from NSW?

Does one put an extra $30 onto the item price just in case someone from WA buys the item?
