I've looked through the previous posts but dont see anything of use to me. Is there a way to get notifications for when a game in your wishlist drops in price? I've never had this in all the years I've been here and have missed a few sales. Without a notifications it seems the wishlist is only half as useful as it should be.

There is no notification. Just a wishlist entry for this feature with tons of votes... hopefully it will get realised someday...
