Flat Shipping Rate Option Remove, when Free Shipping is active for OC versions 3.X
If you enable the Free Shipping extension from admin, you might wonder that you still get the Flat Shipping Rate option even when the user is eligible for Free Shipping. The user has to make an effort to select the Free Shipping option which neither of us would like to.
This OCMOD removes the Flat Shipping Rate option when the Free Shipping is applicable and displays the Flat Shipping Rate option when not.
Simply download the zip file and upload via Home=> Extension Installer upload.
NO CORE FILE IS BEING OVERWRITTEN.
Mail to firstname.lastname@example.org if need any support or help.
Enjoy the free work :)
