I think it might be free shipping for Lowes members, wonder if @ckmk47 had a Lowes membership or signed in when checking out.
I just tried it. No dice. Still only truck delivery.
Good thought, though.
Now I checked at a store near a friend in Philadelphia. They have it for pickup. But the set is $30 !
But in Florida, it's still $12.50, with $84 truck delivery.
