This constitutes as some serious planning but if you preorder Madden NFL 11 from Walmart.com, you’ll get a $20 gift card when the game ships on August 20th.

The $20 gift card is good for the Xbox 360, PS3, and Wii versions. You can get a $10 gift card with the purchase of the PS2 or PSP versions. This offer is only good through Walmart.com’s website and the gift card must be used online as well.

The deal is good “for a limited time, while supplies last.”
