I noticed on the Front page about the Thea 2 giveaway
But, every time I click it, it keeps taking me to a list of games that are on Sale

Also, when I locate the game, it show's the option on the give away; but when I click that it just puts me back to the front page
Am I doing something wrong?

Scroll down on the main store page. You can claim the giveaway below the reccomended deals.

Thanks, Yup; I found it

It also tends to have a green CLAIM button and a countdown timer... the top banner/ad wouldn't have the timer.

edit: Nevermind, it does have a countdown timer at the top... Oh well.
