Our combined postage works this way.
$free for first item send standard mail your risk.
Each additional one similar in size is additional $free per item which is at half rate.
But to get combined postage they must all be paid as a bulk lot not individually.
Please advise if not already combined for an update before paying.
Now if you want REGISTERED post we charge $4 per parcel.
We leave feedback and mark sent as we do each printout when processing.
It can take a few days before posted as we listing lots at the moment
