This option will save you having to send to countries that you do not wish to deliver to. When purchasing and adding their delivery address the customer will only be able to choose countries you select to be in the drop down.
To choose which countries can purchase from your shop, please follow the steps below:
Log into your 123-reg Online Shop package.
Select Country Settings from the dropdown.
Click the Countries tab.
Under the heading Country there is a drop down bar, from there choose which countries you would like to be able to purchase from your shop. You can use the Sort Order column to order the list of countries, so, if your customers are primarily from one country, you can have that at the top of the list, so its easier for them to select.
The higher in the list you wish the country to go to, the lower the sort order number you need to give it.
