Hello,
1. Thanks for the temporary back-end access, we just checked how you configured your payment and shipping methods, and it seems you actually don't have any "Driver" shipping methods and that your "Australia post" shipping method is unpublished, that's probably why they don't have access to that shipping method.
2.
I want customers with a delivery postcode between 6000 and 6199 not only to be able to chose between "Driver" and "Australia Post" as a delivery method, but also be able to chose between "COD" and "Square" if they chooses "Driver". If they choose "Australia Post", obviously, they should only be able to pay with "Square".
In that case you should :
- Remove the "Shipping method" option through the "COD" payment configuration page
- Set the "Shipping method" option to "Australia Post" through the "Square" configuration page.
- Publish the "Australia Post" shipping method via "Hikashop->System->Shipping methods"
Kind regards,
Mohamed.
