From John Scalzi (who’s one of GRRM’s competitors in the Best Novel Category at the Hugos for his novel, Old Man’s War), we learn that those who pre-order his forthcoming book about writing from Subterranean Press and mention him and his blog, “Whatever”, in the comment field for the order will get 30% off their entire order (for most items; A Storm of Swords, for example, isn’t part of this special deal). Which means you could also buy the limited/lettered editions of Fevre Dream or GRRM: A Rretrospective all at 30% off. It’s a great opportunity, which comes to a close after tomorrow, so order quickly!
More information can be found at Scalzi’s blog.
