Robert Plant on his Led Zeppelin royalties... in Led Zeppelin Master Forum Posted February 23, 2010 · Edited February 23, 2010 by ledwallett Were they actually ever for sale in stores does anyone know? I See these on eBay all the time. They sell between 40 and a 100 bucks depending...a lot of the listings claim that it was never released but used as a promo item for radio stations and record stores and such. It was released. I have one.
