I have a range of products that are now stocked in Ireland and i have distributors in Ireland to deliver said items. Problem is....

I offer free delivery on these items and can also delivery free in Ireland and UK, but only on these items, all the other items in my cart (or the majority of my cart) i can not deliver to ireland.

question is... how do i make it so that these items i have that i can distribute in Ireland can be checked out in Ireland, but not anything else??

Thanks
