Regarding shrinky dinks: We did some Disney ones for Jean Bean's last birthday. Found them in the toy section of Walmart.
Regarding Excedrin: I understand the company is going to have product on the shelf later this year, but they haven't been clear as to which product will be first (Excedrin, Gas-X, etc.) It's all that helps DH's headaches, and no, the generic stuff is NOT the same. It has unpleasant side effects for him. Currently he gets what we've hoarded, I get to use the generics because I don't get the side effects.
As for what I miss that I can't get anymore...Anyone remember Wuzzles? I had one I loved until it fell apart, the panda-beaver one. My sister had a bumblebee lion. I wish I could get some of those crazy little animal crosses for my kids!
