Amazon: Save $10 on Monster Hunter 4 Ultimate pre-order

Update (9/23): Best Buy has corrected its price and is no longer taking pre-orders. However, strangely enough, Monster Hunter 4 Ultimate is available on Amazon for $29.99.

Best Buy appears to have made a price error with its Monster Hunter 4 Ultimate listing. It should cost $39.99 when it comes out next year, but the retailer has the game available for only $29.99. You can place an order here and save $10 while the mistake remains in place.
