I suggest that you normalize the section names to a common language, e.g. offers (you can set title and posibly also URL if you want in front matter per language)
With that you can do:
{{ $section := site.GetPage “offers” }}
{{ range $section.Pages }}
{{ .Title }}
{{ end }}
{{ end }}
Or
{{ $section := site.GetPage “offers” }}
{{ range $section.RegularPages }}
// …
{{ end }}
{{ end }}
