No. This is a first.

I can't think why it should... I've no reason to *deny* negative amounts.

It should be possible (he says cautiously), and no, you haven't missed a config option.......

<a little later>
I've spotted the problem, It seems the program is making use of the handling fee values as part of a validity check...

Handy with a text editor?
load /includes/modules/shipping/ozpost.php into editor

At or near line 467 you'll see:

Code:
  if (  (($quote->cost > 0) && ($handlingFee >= 0)) ) {  // valid quote
Alter this line so it reads:

Code:
  if (  (($quote->cost > 0) && ($handlingFee != -1)) ) {  // valid quote
Save the file, then enter your negative handling fees.. use ANY value except -1

As for returning to $0 ... the line that follows the one just edited is a simple formula that adds the shipping and handling figures, so add another line after that that reads something like

if ($cost < 0 ) $cost = 0 ;

... resave the file and give it a try.
