At $13.99 with free shipping (affiliate link), it appears to be the lowest price by a significant margin compared to other stores in the United States.
Update: NewEgg has now listed the game as out-of-stock.
And, considering the game includes the Spec 2.0 update on-disc, along with a PlayStation Network voucher for $20 worth of the game’s DLC, it’s an attractive offer for those who have held off purchasing the additional content.
Meanwhile, Walmart’s online store appears to be completely out-of-stock of all copies of the game, with inventory limited to their physical retail outlets.
Thanks to mcfizzle for the tip!
