A thread for us non-Kindle owners here in old Blighty
Google seem to be have reduced the prices of Picador's 40th Anniversary Editions of eBooks:
https://play.google.com/store/search...r+40th&c=books
Some good stuff there, including "American Psycho" for £1.99, and "All the Pretty Horses" and "White Noise" for £2.99.
Speaking of Don Delillo, Kobo are selling "Underworld" for just £1.00:

booksonboard.com seem to have dropped their prices on the RSC Shakespeare eBooks, making them about a pound cheaper than their nearest competitors although personally, I'm tempted to wait and see if Kobobooks ever get them in stock so I can get them with a discount code

I can't link to them all directly due to the silly way their site works, but search for "Eric Rasmussen" on
http://www.booksonboard.com/set_country/?c=gb . (
Update 27/3/12 - these have gone up by about 50p, but still seem to be the best value I've seen).
Google Play are also doing a "Play Dead" promotion focussing on the undead, including the acclaimed (albeit naffly titled) "The Last Werewolf" for £1.99:
