I released an extension that adapts the OXID shop to North American standards (including support for such things as taxes & addresses). It’s more than just a module because changes were necessary to several template files. As a result, a custom theme must be used, but this ‘theme’ is really just the Azure them with necessary changes made.
@klekos, it is here now: https://github.com/OXIDprojects/6vC-NA-Shop. Also, @spurvis is not available any more. Be aware that this post as well as the module is ~ six years old. I could imagine that it doesn’t work with a present OXID version. Maybe you can use it as a “line of thought”.
