Magento Connect: Tweakmag Shipping Extension
Enhanced shipping methods to allow more flexibility and alternative methods.
Tweakmag Shipping (TMS) provides enhancements to the existing shipping methods provided by core.
For this initial release I have added Australia Post as a shipping method. This will automatically calculate shipping costs based on origin postcode and where the order is to be delivered too. It will also estimate the time that it should take for delivery.
You can also control the minimum and maximum order values that must be met for the shipping method to be available.
