Good afternoon,
The essence of the question is this:
There is a store on joomla + virtuemart, it is located in the Moscow region, it is required to make a region for the same store, for example, St. Petersburg, they will differ only by the phones indicated on the site and the addresses of the organization.

Answer 2

1) Are you sure that you need them to differ only in phone numbers and addresses? :))
Shouldn't the title/description of the pages be different?
Shouldn't robots.txt with the host directive be different?
Sitemap and links in it should not differ?
and so on ...
Look at the material , I think it will come in handy for understanding.
