All the ebooks of the
Modern Masters of Science Fiction published by the
University of Illinois Press are currently discounted (only $3.08 each) at Amazon, at least when Buying from Spain:
Greg Egan, by Karen Burham (this was published today, by the way)
William Gibson, by Gary Westfahl
John Brunner, by Jad Smith
Gregory Benford, by George Slusser
These are, strictly speaking, non-fiction but since I think that they will especially appeal to SF readers I decided to publish it on this thread (if it is incorrect, please move it to the non-fiction thread).
Update: Kobo seems to have matched the price (and they are couponable there), at least as seen from Spain
