HI!
Unfortunately, I'm actually already signed up at that website (I have a little one also)!
Have you checked on ebay? They have a lot of formula and diaper coupons.
Do you have any Mom's Clubs (
www.momsclub.com) near you that you could join or another mom's group? I know we used to have some women inour group who always seemed to have coupons, formula, etc that they wanted to give away.
