Steam Bundles

I've been looking for something and 2 things are bothering me:

http://store.steampowered.com/app/70110/ - Bundle Stars The Hacker Bundle - 2,85€

Hacker Evolution, Hacker Evolution Duality, Hacker Evolution Duality: Hacker Bootcamp, Hacker Evolution Duality Hardcore Package 1, Hacker Evolution Duality: Inception Part 1 DLC, Hacker Evolution Duality: Inception Part 2 DLC, Hacker Evolution Duality: Inception Part 3, Hacker Evolution: Untold, Hardcore Package Part 1 / for Hacker Evolution, Hardcore Package Part 1 / for Hacker Evolution: Untold, Hardcore Package Part 2

is still visible but already impossible to buy since it is not available anymore on http://www.bundlestars.com/all-bundles/the-hacker-bundle/

http://store.steampowered.com/app/21090/ - F.E.A.R. Collection - 13,74€ (Halloween Sale)

F.E.A.R. 2: Project Origin, F.E.A.R. 2: Reborn (DLC), F.E.A.R., F.E.A.R. 3, F.E.A.R.: Perseus Mandate , F.E.A.R.: Extraction Point

is still available.
However on http://www.bundlestars.com/all-bundles/fear-bundle/ it is priced as 7,29€

Any ideas why?

PS. Hardcore Package Part 2 / for Hacker Evolution: Untold is 101% off sale, so if I buy just single base game will I be able to get that DLC as well?
