The Xbox Live Marketplace Deal of the Week is Ubisoft's DLC pack for last year's Prince of Persia.

Starting on October 5 for one week only, Prince of Persia's Epilogue will be 560 Microsoft Points ($7), 30 percent off of the regular price.

Epilogue is a downloadable pack that offers a new environment called the Underground Palace, a new power that temporarily reconstructs destroyed parts of the landscape, and more. It originally came out earlier this year.

Sadly, this is only available for Xbox Live Gold members.
