jensmanchester No thats not what im getting at..what im trying to say is like I said above- how the more expensive pre paid bags are probably used for convenience because the item would definitely fit in one no thought needed.. instead of seeing if it could fit in a smaller one or another form of cheaper packaging. I do realise this- If Australia post charged $10.00 to send 3 second hand Barbies then how can you expect it be be posted any cheaper as it is Australia Post that determine the cost.

The reality is that in most cases, particularly for parcels over 500g, the cheapest way to send them is using a pre paid satchel.

Parcels sent within the same city are cheaper if not sent in a prepaid satchel.

Parcels sent within your own state may or may not be cheaper if not sent in a satchel.

Virtually all parcels over 500g sent interstate are cheaper if sent in a prepaid satchel.

Not only are prepaid satchels convenient for sellers but more often than not they are cost effective for the buyer.
