Does preordering mess up your ability to pricematch? It seems like it shouldn't, but I wonder if the deposit messes things up (in my mind: "But you only paid $X for the game - the rest was for your deposit.")
If it matters, I'm thinking about BB (they are the nicest in my area about PMing, I've found).
