I get my books from a variety of sources. Because the majority of my books are on Kindle, and from bookbub or fussy librarian (freebies and cheap), the majority of my books come from Amazon. When a book comes up for bookclub, I look at the library first. If it’s going to be a long wait, I will look on Amazon next. Usually, I can wait for the library hold, though.
I look at the library book sales for series pieces that I need to finish. I have several series where I have books 1 & 3, and I keep looking for 2. I am patient, unless I am mid series. Most of these books are $1 each, so it’s worth the effort.
I can’t wander past a bookstore without going in. I tend to purchase at least one book whenever I go in, and it’s usually something I’ve been contemplating for a while.
Finally, I have a book of the month subscription, where I get the new releases.
I use a variety of sources to fulfill my need for books. My book addiction.
