"Add To Wish List" in the Mac App Store? Does anybody know if there is a way to "add to wish list" some apps at the Mac App Store and get noticed when their price drops just as in the iTunes Store?

Thanks in advance!
There is no default mac app store wish list, all though, there are some 3 party applications and websites that allow you do track apps prices and add them to a wishlist. One of them is: http://www.appshopper.com/.
