You can never rule out getting ANY game for 75% off. It is possible, very much so. In fact, someone even got the Madden CE for 22.48. That's fairly impressive right there.
Yea, if something isn't moving off shelves quickly at retail it will get clearanced regardless of what game it is. Especially at this time of the year when there are a ton of releases for the upcoming holiday season. Most games sell the first few weeks after release and will only sell after that point if there is a promotion or a price cut. I just see Pure as a game very similar to Grid where they both got good reviews, but ultimately are just going to get lost in the shuffle.
