Don't know if anyone else has noticed (Did a search and could find nothing on it) But I was just browsing the Dragon Age DLC and noticed a fair chunk of it is on sale, for example:
Leliana's Song, was 560 Points, now 280.
The Darkspawn Chronicles, Was 400 Points, now 200 Points.
Awakening Expansion, Was 3200 Points, now 1600 Points.
Hope this is a help to someone!
