Albert Heijn launched a Facebook app with an animation of two sustainable products battling for the most Facebook likes. Fans can vote by liking their favourite product. The sustainable product that receives the most likes will get a 50% discount in stores the week after. You can vote here. I'd vote for the fish, if only because the pun-joke about the rod spoke to my love of idiotic puns. Like "Boodschappen met een boodschap". Seems I'm not the only one as the fish is currently leading with a thousand odd likes.
