Hi @itmonitor
Thanks for reaching us.
To sell different product on different countries you need to create different feeds. And to distinguish products, there should be categories or any custom field. For example, you would need to add a custom field “Country” and then populate it with the country name you are selling on.
Once you have the country custom field, you can filter items based on the country fields value, but this filter can not be done by the Free version.
Once you have different feeds containing different items based on the Country custom field’s value, you can upload those feeds targeting different countries on Google merchant center.
To know how to sell in different countries, please, follow the documentation by GMC from here or find more from GMC documentation.
Please, let us know if the above helped you and feed free to reach us again if you have any further queries.
Best regards,
