Humble Bundle frequently has nice bundles of genre fiction or comics by specific authors. I've picked up large sets of Ebooks from them over the last few years by numerous authors: Ursula K. Le Guin, Robert Jordan, comics by Moebius, and recently Timothy Zahn and various scifi/fantasy authors with careers spanning decades.

I'd be re-reading Tolkien's _Old English Exodus_, but proofreading the typos got to be too much.
