X-link to the DRM-free megathread for the latest StoryBundle:
The New Worlds Bundle curated by Steven Savile features a mix of new and backlist works offered as nearly-complete short series by new and established authors, including Jody Lynn Nye's humorous Mythology fantasy trilogy originally out from Questar, Craig Shaw Gardner's humorous fantasy Ebenezum Trilogy originally out from Ace, Melissa Scott's Silence Leigh sci-fantasy space opera trilogy originally out from Baen, and many more.
If you pick the top tier, you can get a total of 30 books for just $15, some of which are pretty good books at that (Scott's Silence Leigh titles were apparently nominated for Locus and Lambda awards back in the day, and she herself was a Campbell Best New Writer winner), and I've personally read and liked the Gardner books, although they are on the decidedly fluffily farcical side, so YMMV.
