Dunno how prices look for the bundle games in your country, but here S&S has never dropped below the price of the bundle and Zero Caliber has only barely gone below it, so seems like it'd be worth it just for those two.
I also think I Expect You to Die and Creed are also worth playing, and you don't have those yet, so I'd grab the bundle and wait for a sale on Population One.
