Some of our customers use the Australia Post Real Time Shipping method and we discovered an issue where Registered Post International was not calculating correctly. Here is the response from CS Cart:
“The fix was released recently. I have applied the necessary changes to the aup.php file located in the shippings directory of your CS-Cart installation, and the problem is not reproduced anymore. The shipping rate for the Registered Post International service is correct now.”
I have attached the aup.php file for anyone who may need it.
We use CS Cart 2.4.5 so if you are on 3 it may have been fixed already.
NOTE: If you want to check that the Real Time Shipping is calculating correctly, check it against this Calculator: http://auspost.com.au/products-and-services/postage-assessment-calculator.html
What is location/path for shippings directory?
