It's been 30 years since U2's War album, their third, was released. It's currently only $5.99 in iTunes for the remastered version or $15.99 for the Deluxe Remastered Edition which adds 4 remixes of New Year's Day and 3 of Two Hearts Beat as One, in addition to other tracks not included on the original album.
