Amazon offers Prime members Megadeth's Countdown to Extinction Autographed Audio CD for $7.54 with free shipping. (Non-members can spend $35 to qualify for free shipping; otherwise, shipping costs $3.98.) That's only $3 more than the lowest total price we could find for the un-autographed version. This 2004 remastered reissue CD is signed by Dave Mustaine and features four previously unreleased bonus tracks (15 tracks total).
