Thank you - I was able to set up the rules easily - but I'm afraid I'm missing something very basic.... I need to add Shipping to the Order Summary, yes? The bottom half of my page with the order summary is missing online now, so I'm assuming that (deluded myself into thinking it would magically appear if I set-up the rules....)
I attached screenshot of one of the rules I set-up (in case) and what the cart now looks like..
Thanks so much!
