In cooperation with the Austrian Postal Service, we developed promotional stamps: real stamps whose value corresponds exactly with the price of the products shown. These stamps were given away on the cashpoint of Penny-Supermarkets as loyality rewards. For every purchase of 20 €, customers received stamps amounting to 1 €.Placed on regular letters, the stamps managed their way even into those mailboxes, where advertising was not welcome.

All of the 100,000 produced stamps were given away to customers within a few days. Some of them found a new home in an album of a philatilist, but by far the largest part was put on letters and got into the mail of people across the whole country.
