In their “Countdown to Black Friday” event, Amazon is currently giving $40 store credit when you purchase a qualifying Hero video game bundle from offered in their Hero Bundle Deal.

For a limited time, buy one of the qualifying games on their lists — a version of Band Hero Super Bundle; DJ Hero Bundle with Turntable; or Guitar Hero 5 Guitar Bundle Game — and you’ll get $40 Amazon store credit. Bundles are available for Xbox 360, Playstation 2, Playstation 3, and Nintendo Wii.

The offer is only for qualifying titles shipped and sold by Amazon (meaning, NOT a third-party listing on Amazon), and is limited to one per customer. Offer ends on November 27, 2009 11:59 PM Pacific time.

After you purchase the item, you will receive the store credit in your Amazon account within two business days after your order ships (you’ll be notified by email). Be sure to click the link for “Rules and Restrictions” before you purchase (it’s the standard fine print, just wanted to give you a heads up that these exist).
