Magento Override Shipping Methods

  • In this open etc/config.xml file and find appropriate model for it. In the model file you will find default methods attached to the carrier.
  • If it’s been overridden, then the simplest way to find it is by a doing file search in your magento directory by «flat rate» or «free shipping».
  • However your other shipping carrier and methods like fedex, ups, usps etc are defined in app/code/core/Mage/Usa.
  • Your default shipping method flat rate and free shipping are defined in app/code/core/Mage/Shipping.
  • All of the above
