I have a backlog already but I still bought Guacamelee, The Witcher 2, Brothers - A Tale of Two Sons, XCOM Enemy Unknown, the Bioshock Triple Pack, and Monaco for $38, which would have been $155 full price. 75% off!
Technically I also got The Bureau bundled with XCOM, but who cares about that. Only picked it up because the bundle was actually cheaper than XCOM alone.
