    Default Re: exclude certain products from free shipping

    i would suggest that trying to merge code that is over 15 years old is not a good idea for the following reasons:

    • the code is 15 years old.
    • overwriting core ZC files is also not a good idea

    i would use an observer.

    i think if you review the observer in this thread, you could very easily modify that to do what you want.

    best.
