A couple of weeks ago, Target had (and may still have) a couple of deals going on:
- $190 for 12 GB with some Call of Duty game bundled (good deal if you're planning to upgrade to 1 TB, which costs around $80 or $90)
- $240 for 500 GB with Lego Batman 3 (disc) and the Sly Cooper collection (digital, three games)
And then you can take off 5% with a Target credit card, which makes the second bundle cost close to the price of the Gamestop deal you're seeing.
Just a couple of extra options to consider. I'm not sure whether the sale is still going on, but if not, I bet it'll come back. I've seen other console deals pop back up a couple of weeks after expiring.
