I went to Best Buy over my lunch break and picked up GTA: SA. While I was there one of the guys working mentioned that I could pick up a Greatest Hits game for just $5 more.
On another note, I just picked up the second to the last copy at my store (Lafayette, IN) and while I was looking for a Greatest Hits game, someone else snagged the last copy. I wonder if there is going to be a shortage??
