Been boycotting Nestle for decades. One line of products most USians don't know is owned by Nestles are Contadina tomato products.

One of the best websites for boycott news in the US is Boycott Action News at Co-op America's website:

Their "Responsible Shopper" search engine, co-sponsored by Working Assets, is very valuable.

Also, the Global Exchange Sweatshops site has information on socially responsible shopping here:
