The “Red Bull Air Mail” campaign is running across limited edition sleeves of Red Bull’s 250ml four-packs which, once opened, will become a postcard that shoppers can give to friends or family.
The postcards feature a code to be entered online to redeem a four-pack of Red Bull.
Red Bull said the value of multi-packs is growing at 41% and now is the “perfect time for retailers to stock up”.
The campaign aims to “leverage existing users to drive new multipack users, as well as maintaining 4-pack distribution and rate of sale in the impulse and grocery channel, which in turn will contribute to the overall growth of the sports and energy category.”
