Deutsche Post did not just have to fund the purchase and installation of pakstations and train employees how to place parcels in them for pick-up by customers and remove parcels for processing but it had to fund a sizable marketing campaign to convince the public to use them. The two videos illustrated that marketing a new process of sending or receiving parcels is not an inexpensive proposition.
This web delivered commericial illustrates the problem of not being home when the delivery happens.
This video of a song was most likely used in shorter bits in commercials on the web, television, and radio. Since the Pakstation was introduced sometime before 2007 with a second order of 1,500 placed that, I am willing to bet that almost as many Germans can sing the chorus as can sing McDonald's big Mac jingle.
