often these were singles, B-sides, non-hit album tracks, or otherwise obscure material, all designed to arouse interest in the artists' regular albums. Warner advertised the Loss Leaders albums by inserting special illustrated inner sleeves in all of its regular album releases, listing all of the currently available Loss Leaders and including an order form. Each Loss Leader double album was priced at $2USD, significantly less than a comparable regular-release double album of the time. The first Loss Leaders compilation was The 1969 Warner/Reprise Songbook, featuring a wide range of artists from Miriam Makeba to the Mothers of Invention; the last of the original series was the punk & New Wave-themedTroublemakers in 1980.
