How do you increase consumption among your die-hard fans who are already buying Hellman's for their sandwiches? Easy, and a little big-brother-ish, Hellmann's turns your receipt into a personalized recipe by combining the products you just bought into something tasty. Shoppers were pleasantly surprised, perhaps tried something new, and sales of Hellmann's increased in teh supermarket chain where this was done. I reckon Ogilvy Brazil have a good shot in Cannes with this one, what do you think?
