Most times these books are only free for a day or two, so you have to grab them while you can. Worry about whether you really want to read it later if it seems interesting. And be careful, they can change from free to not free at any time. I have also decided to list books for no more than 2 days in a row to avoid cluttering up the posts, unless there is some reason I think the book deserves extra attention.
Free From Stackpole.
Stackpole puts a book or two up for free periodically. I have read several of their free books. Some interesting stuff. Most of what I have seen is WWII German military history, with varying quality of translation, some other military history from lesser known units, along with some fishing and other outdoors oriented books.
