I was in a Best Buy in Rockville Maryland roughly an hour ago, they had a few copies of Odin Sphere and one Copy of Grim Grimoire. I thought about getting Grim Grimoire, but I already have a large backlog of games to get through and didn't feel like adding another one to it, even if it does turn out to be rare.
I only checked the price of Grim Grimoure (39.99).
So, copies are out there in stores, but not in the price range you are looking for.
