This thread is for pointing out free and bargain DRM-Free ONLY titles to each other. Please don't post any self-published books (unless you have read them yourself, think they are excellent, and you're not connected to the author in any way) and please do a search before posting to avoid duplicates.
As always -- if a deal could span multiple subjects, please cross-post to ALL applicable deals megathreads.
This is pretty much the one time when double-posting is not only allowed, but encouraged. Seize the opportunity!
Keep in mind, most freebies last only for a day or two, so grab them fast!
Permalinks:
- Open Books (by calibre) -- collects info about DRM-Free books, some are free or bargain-price.
- Tag search: drm-free ebook -- past and present single-thread deals (or otherwise) marked as DRM-Free. Remember to add this tag to any other threads you find about DRM-Free deals.
Some people are ideologically interested in buying ebooks only if they are DRM-Free (no one here needs to be reminded of why DRM can be annoying 
), but it can be difficult to tell which ones those are in the other stickies.
