I have tried to follow, however in my cart page I already have a shipping cost before I get to checkout. This is added by the add to cart button.
I am also unsure where on the page I put the Checkbox, Billing or shipping info area or does it make a difference??
Does it matter where I put the hidden form element code?
I have put the session variable on with the other session variables.
Allowing for local pickup doesn't alter the Grand Total result
In the shipping rule (see Pic) I cannot select "<>" with a value of 1
