*Game goes on sale on Steam*
E-Mail: A game on your wishlist os on sale.
Phone notification: A game on your wishlist os on sale.
Phone call: Have you heard our new offer where a game on your wishlist os on sale.
Telegraph: ALERT. STOP. A GAME FROM YOUR WISHLIST IS ON SALE. STOP. LOGIN NOW TO SEE IT. STOP +++
At least the email has the decency to tell you which game is on sale. The Steam app notification just says "a game on your wishlist is on sale!" and when you tap on the notification, it just opens the app; it doesn't direct you to your wishlist or even to the store :/
