Super Mario Galaxy 2 comes out 5/23 and I know that a lot of people are excited about it. If you reserve it now for $49.99, Amazon is offering $20 credit towards to purchase of another video game! Super Mario would qualify for both free shipping and price guarantee (you’d get the difference in your money back if the price goes down) and you’ll get your promotional credit within two days of the shipment of your game.
