My very favorite dairy (local to me, but with products available across the U.S., I think) has all sorts of nifty resources.
Go to Stonyfield Farms and sign up for coupons, “Moosletters” and more. (Thanks, Anne!)
Stonyfield also hosts the Menu for Change resources, which should be required reading for any parent allowing her child to eat school lunch. (Yes, my local school administration hates me. Instead of “The sky is falling!” I run around screaming “There’s hormones in our milk!”)
