Henry Moore Foundation review for SMART Shipping Rates & Rules

Downloaded this as I wanted to hide the 'Ship to' option in checkout for products we only offer as collection. Couldn't get it to work, even after talking with their support (they tried to be helpful but were too vague when it comes to Shopify terminology to be of use, and were slow to respond - twice my help session timed out because they hadn't replied). Either the product is badly worded as to what it does, or it's broken. Might work better for other purposes, but I tried to configure queries in a dozen different ways, all with zero affect. Waste of a couple of hours.
