- The customer chooses an address.The received prices of the rates does not include the extra fee for the available options.
- At the shipping method section ot the checkout page, the customer can choose some option, and when she clicks the button to proceed to the payment methods section, the recalculation of the shipping rates must be triggered again.
My goal is to trigger the recollecting of shipping rates in
How can i achive this? I've tried the steps in the thread(https://stackoverflow.com/questions/5671787/unset-shipping-and-recalculate-totals-in-magento), but without any luck.
Thanks in advance!
