Walking through my local Best Buy I decided to see about picking up some old Metallica albums.  Of course, they had a ton of copies of the new Death Magnetic.  Interestingly, I saw a CD that had a sticker offer a free digital download of the tracks for Guitar Hero with the purchase of the CD.  Seemed like a good deal.  However, it cost $39.99.  The CD is normally $13.99 at Best Buy.  The DLC costs $17.99.  So... basically Best Buy is allowing you the privilege of paying $8 more to get both.  Thanks guys.
