my experience with marco is postage costs arent cheap, but i was given tracking number, when i chose usps postage and it did state when it ended up in Australia.
one country that has very cheap postage is china, man they ship things for almost nothing, must be nice to have a postal service that cheap. icouldnt send stuff from the sunshine coast to brisbane as cheap as it costs for some one to send something from china to me here.
