There have been many over the years.
Most originate from Germany but some are also exclusive to other regions like the "Goodys" figures which were only available in Greece.
Another example is the "Nordsee" sets which were available from a chain of fish restaurants. Going much further back there were the McDonalds figures in the US (1980s, I think).
The above promos are all food-related but that is purely coincidental because they do promos for all different types of companies and organisations.
Try searching "Playmobil Promotional" or "Playmobil Promo" on eBay.
