I have started using couriers for some items. I have been checking the cost of AP verse Courier. For items over 1kg courier services normally work out cheaper. I hasve noted on listings in this category that the item will be sent via courier so no PO Boxes. with a note if this is an issue contact me.

I have not explored the many service available, however have been happy with sendle.  Easy to use as everything is handled online. Just have to be careful as they are expensive to remote areas so I then revert to Aust Post.  Hope this helps.
