Steam coupons for "extra purchase" (game packs)

I came across some Steam coupons, that can be also applied:

• 80% OFF Giana Sisters Twisted Dreams – to buy "Giana Sisters Twisted Bundle"
• 90% OFF Penguins Arena: Sedna's World – to buy "Action Indie Pack"
• 90% OFF Vigil: Blood Bitterness – to buy "Puzzle Indie Pack"

Does anyone know: are there any other coupons/games that allow to buy a game packs with the appropriate discount?
