I got tipped off to this a few hours ago, runs for 3 more days through the weekend.
Some stuff like Tomb Raider Temple of Osiris is 80% off ($2), and on the low end, the minimum is 50% off (Final Fantasy XIII-2 for the first time that much.)
I snapped up FF13-2, been waiting for it to hit $10 in a deal to give it a go.
