Found this site recently (link), not that I am thinking of planning, saving or getting married. What struck me about it was the obvious link and connection between the two actors – a wedding planning magazine and a savings bank.
The site incorporates the two parts nicely into an integrated whole, and its is difficult to see where the border between the two collaborators goes (always a good sign). In addition, it comes across as customer centred, with a nice customer experience. Its not particularly pushy, for either the magazine content or the savings bank, which I think gives it a nice image. The tone of voice is helpful, encouraging, positive and optimistic, which fits the marriage plan goal. The collaboration is aimed at making things easier for the user, which it does nicely, and probably leads to nice additional sales of both the magazine and financial services.
This is a typical example of actor collaboration to satisfy customer needs, and I hope that I come across more of these in the future.
