Clearing coupon and expedited boxes
I have a coupon code and an expedited boxes on my site set up following following your tutorials.
If a customer decides to clear his cart (but without logging out) and start again and has used these two boxes, when he adds an item to the cart and checks out it still shows the reduction for the coupon and the expedited charge from the original cart.
Also they may decide that they don't want expedited delivery after all, so how would I go about clearing the box as once they press checkout button the checkbox clears itself and the charge is shown even if they clear their cart and start again.
Is there a way to reset these two boxes if they decide to empty their cart and start again?
