I will have some downloads, and I am considering adding an option which will allow users to have an extended download validity as a chargeable option.
I can probably use the giftwrap snippet functionality to add the option in the checkout.
Although I would prefer to have it as a listed option, because that gets buried in general shipping and handling.
Main question is how would I extend the validity for that specific user/download, without changing the default periods ?
Any thoughts very welcome
