Is it possible to dynamically specify the shipping method for Magento's free shipping module?
This is the logic I want to setup:
To US: Free shipping through UPS ground. To Canada: lowest rate from USPS or UPS APIs
I saw this post which provides a way to retrieve the cart's shipping methods: Magento : Get all Shipping Rates
$quote()->getShippingAddress()->getGroupedAllShippingRates();
I was thinking finding a hook in the checkout process, finding the lowest quote, and adding it to the notes. I am concerned about changing the shipping method as it may affect the price.
