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 decided to list books for no more than one day to avoid cluttering up the posts, unless there is some reason I think the book deserves extra attention.I have also decided to consolidate to a single post, instead of sometimes splitting them up by subject matter.
