GAF ‑ Store Pickup & Delivery

We have some peculiarities in our Shopify set up and so checkout was a problem with the standard Shopify set up. I emailed GAF if they could overcome these issues and GAF responded quickly with the affirmative. That sometimes isn't enough because when app providers then actually dive into problem they realise they can't sort. However GAF dialled on with support and dived in and got a result. Our problems were sorted in 20 mins. Thanks GAF
