Also, If you have a Toys R' Us nearby, they would give you the lowest price for it.
Toys R' Us $150
Target $160
Walmart $160
Everywhere else as far as I know $199 (gamestop and newegg/fry's for sure is 199)
Also non-game related stores will sometimes hold items if you call ahead, so I'd give Target or Toys R Us a ring ahead of time and see if they can put your 1 out of 4 on reserveOr order it online. That's probably your best guarantee (minus the downside of shipping)
Guys try not to double post. If you have something to add, just edit the first post.
