I couldn't find this at the first five stores I visited, so then I got smart and checked Gamestop's website for availability. I had no problem finding a copy this way.
While I was buying the game, the Gamestop clerk said they had gotten around 25 copies of the game. I found this interesting...
I know some people who would kill for a $5 Tetris Attack. I say go for it.
I nabbed Ogre Battle 64 the last time they did this sale, but it was cart only (all my games were).
