I figured out a workaround. I checked the box that it’s a physical product and put the weight in at 1000 pounds.
I then created a shipping option called “shipping not applicable” at no charge.
I then created a shipping rule that offered free shipping for any item that is 1000 pounds up to 100,000 pounds.
No other product that we offer weighs more than 1 pound and nobody is ordering a thousand of any of our products so the rule will never affect our shipping charges other than for this 1 item.
If anyone else has any other ideas, we will keep this work around activated.
