Amazon is holding a gaming-focused set of Gold Box deals today, including the utter steal that is Bioware's recent RPG release Dragon Age II for a third off at $40.
Dragon Age II will be at that price for the rest of today, but other 'Lightning' deals will only stick around for a couple of hours and then disappear.
At the time of writing, Need for Speed: Hot Pursuit is also up there for $40, also 33% off, but that deal will flip to something else shortly. You can find the deals over on the Golden Box page on Amazon.
If guesses from Thrifty Nerd are correct, you can expect Bulletstorm, Turtle Beach Earforce headsets, Dead Space 2 and You Don't Know Jack all to show up on the Lightning deals shortly.
