[Suggestion] Skin Wishlist for in-game store. Notifies you when a skin on the wishlist is on sale

Skin Wishlist for in-game store. Notifies you when a skin on the wishlist is on sale.

Could even email you that a skin/champion/summoner-icon/etc on your wishlist is on sale. Would promote more sales, and is a nice tool for everyone. What is there to lose? Steam seems to be successful with this. If a game on my wishlist goes on sale, I tend to purchase it or consider it.
