does this site is reliable?

yeah it's reliable

Yes it is. Bioshock and Lucius are not for Steam, the rest are.

Yeah it is bought twice and got my games no problems.It had some nice sales before.

If you hold your mouse pointer over the game you'll see if the game uses Steam or any other DRM.

Yes, it is. I've bought the Mafia 2 and Borderlands GOTY.

yes but it's only good if you're buying the whole pack instead of 2 games for 12$. Youd be better to trade the games you want instead

yes it is!

Wow, that looks like a neat deal! I'll have to look into it if they have another sale in the future.

Yes, no problem
