I was looking for an addon to allow customers to a select free
shipping option when the shopping cart reaches a certain value.
i.e. when £50 or more is in the shopping cart.
The total orders module provides the free shipping option,
but the other shipping options were not displayed when this
criterion was reached.
I'm currently using 2.3.4BS Gold, but the addons available to
give me this option didn't provide a solution without a lot
of code changes.
This addon uses the table shipping method to address this issue.
