So I JUST learned of this today from our office mail carrier. I don't think USPS did a great job of marketing this. (And the government is supposed to run our healthcare? Riiiiiiiight... excuse me for not getting on board with that - our government is less than what I would call efficient... Anyhow...)
So check it out - go here and promote! Post it on your Facebook - email your friends and family - get the word out!
Basically, the second Saturday in May mail carriers will collect any nonperishable food items left in your mailboxes - so donate tomorrow people!
Read all about it here on the USPS site.
