There are certain products we sell that we cannot (or do not want to) send internationally. Either because of flammable ingredients or particularly bulky items.
At the moment our solution to this has been to create a category message that we set on these products that displays on the product page.
With category messages no longer an option in Cloud MT and with a more rounded solution desired perhaps the following could be achieved:
1) On product detail pages in Cloud MT we could set "Excluded Shipping Destinations". We could then choose which countries to exclude based on the countries that are available in our checkouts shipping options. This would display prominently next to the "Add to Basket" button on item pages and in red next to the item in the basket.
2) If the above is too complex then perhaps just having an option to "Exclude international delivery" on the product detail page of Cloud MT would be useful. This would work in a similar manner on the front end to the above and would exclude shipping countries except for that of the stores location.
