For the time being, I'd like to set my store to allow shipping only to UK addresses, but I'd like to accept payments from everywhere (so people can send gifts to those in the UK).
I have only two shipping methods: Free shipping (which will later become a flat fee) and Collect In-Store. Both of these are set/apply to UK only, but my overall Countries/Regions has all countries enabled. This isn't achieving what I want, as every country is selectable on Checkout2 under Shipping Details.
How do I exclude all other countries from shipping but not billing?
