I would think food banks, the local churches, and/or a women's shelter would be the PERFECT place for this. OR you could list it on Freecycle and have someone that needs it come pick it up. Good for you for giving it to someone that needs it!
Ah, after responding, I just read your update.
With my first two kids (both born in a hospital) I received all the free formula that the formula companies send, plus all the "checks"/coupons. I guess I could have written or called them to tell them no thank you, since I exclusively breastfeed. I didn't. I donated every last bit of it, and gave the coupons to friends. Soon after DS1 was born, we had food drives at my school (I was a teacher before I decided to stay home) for Hurrican Katrina and Rita and that's where the majority of my free formula went. Not the same as WIC, I know, but still....
I think it's wonderful that you are donating it.
