I always do great at local library book sales. I tend to do better with kids books than I do adult books. Which is fine by me. My children tend to go threw books rather quickly. Whether it be a spill on the book, a torn page, or "I don't know where I left it" excuse. These are the books I got yesterday for my kids:
For 12 books, I only paid $4.50! That's only about .38 cents a book! How can you go wrong?
The site I use the most to find local book sales is book sale finder. Just click on your state to get a list of all the upcoming book sale listed by date.
