Found this great website. I'm assuming that it was originally created when the Wii was difficult to find, but now it supports multiple items (more than just Wii related).
I was recently able to find an arcade stick in stock (very hard to find).
Basically, the way it works is:
You find the item that you want an alert on, and it'll email you and/or send you a txt message when it's in stock.

We’re a group of volunteers and starting a new scheme in our community. Your web site provided us with helpful information to work on. You have done an impressive task and our entire group can be grateful to you.
