Make payment option available for one country

Hi,



I want to make my online store to work in one country. So bascially you can only buy a product if you live there (South Africa).



I set my default “Localization” to: South Africa and

I made my “Locations” set to South Africa.



Is this all I need to have my store function in South Africa or are there more settings I need change?



Thank you



Regards

Adriaan
