Amazon has graciously extended their $20 credit on all orders for Final Fantasy XIII-2 (Xbox 360/PS3). Initially, it was supposed to be a launch-day-only deal. Here's what Amazon had to say:
$20 Credit and Order Bonus
Order the standard edition of Final Fantasy XIII-2 and get a $20 promotional credit toward the purchase of items shipped and sold by Amazon.com (certain exclusions apply, including but not limited to Kindle books, Gift Cards, and Amazon Appstore for Android apps) as well as a digital Final Fantasy XIII-2 mini strategy guide. We will send you the promotional code and the link to the mini strategy guide via email within two days after your qualifying order ships. Offer valid when shipped and sold by Amazon.com. Limit one per household. Amazon reserves the right to change or terminate this promotion at any time.
If you haven't purchased the game and still want to (I'm sure there are a few), get moving, because Amazon can change or terminate this promotion at any time!
The sequel, which was released on January 31, 2012, currently holds first place on the Best Sellers in Video Games List as a result of this deal.
