And just for completeness sake

Now if you look at the Aust Post website you will find that Click and Send is simply a process, a process which provides you with most of the same postal service options as if you had handed the parcel or pack over the counter for processing.

If you use the standard (no frills) click and send option, this allows the item to be safe dropped, which is the same if it had been sent regular post. That is if you want to it signed for at the other end or extra insurance cover, you have to pay for it the same way you would if you has sent it registered post.

But then that not the end of the matter because even if it was sent registered or the Click and Send equivalent, that only insures the item for the first $100, but my example was for an item worth $200.  Therefore even if you were correct, if something goes wrong, the buyer is still out of pocket by $100 because they (the buyer failed to pay for the extra insurance.

Then finally of course there is the fact that though initially, PayPal would only accepted receipted delivery services such as registered post as proof of postage, they have over the years been forced to accept others to the extent that today they will now accept just about any documentary proof including an AP receipt showing something was sent to the buyers postcode.
