Got this via email from a friend of mine:
For the first time in its more than 100 year history, Campbell Soup Company is making available to the public specially cultivated seeds used to grow tomatoes for its iconic Campbell's Tomato Soup. The effort is part of Campbell's goal to grow more than one billion tomatoes across the country to support American agriculture.
Through June 21, each household that purchases any variety Campbell's condensed soup and enters the code on the can at HelpGrowYourSoup.com can request a free packet of Campbell's tomato seeds.
Campbell began growing tomatoes from its own seeds on New Jersey farms during the 1930s.
