The auspost module is not calculating multiple parcels correctly, it works fine for up to one box but two boxes or more the postage is heavily overcalculated.

I have my store set up so 12kg is the max weight (but even set to 20kg the aus post limit I get the same problem)

For example sending 1 x 12kg box from Melbourne to Sydney I get calculated cost of $22.50 (correct)
but if I increse that to 2 boxes I get $75.13 (should be $40.05)
3 boxes I get $162.86 (should be $57.60)

Any ideas? is this module buggy?

Also the logout button on my site does not work (default template)

The formula for calculating the cost doesn't work for multiple boxes - it works on averages based on the max weight set in the admin (which is out) then compounds the error by multiplying by the number of boxes.

Firstly clear the Package Tare Weight in the Admin/Config/Shipping/Packing area. Then set the Quantity to 1 in this line in each auspost module you use, so:


becomes:

It's not 100% accurate, but it'll be a lot better than what you're currently getting.

Thank you Simon, that works much better.

Insurance does not seem to work correctly either, it will add the base charge but not the charges per $100. Strangely the international insurance seems to work ok just not regular or express.
