Was browsing the Gamestop sales today and saw (no pun intended) that they had Saw: The Game for $17.99 new on the website. During the recent Game Days sale it was $24.99 so this is a new sale. It doesn't say online only, so even though it's not available online, I'm guessing it's valid in store. Used is still $32.99. Searched the other threads and didn't see this mentioned.
