Thrifty Strategy- Library book sales

Have you ever been to a library book sale? Most public libraries have them a few times a year. They usually sell a combination of books they used to lend out and books that have been donated. You can find some great deals and they are usually well-organized, too. My mom got quite a few books for our daughter this weekend at a sale near where they live. I'm sure there will be several coming up now that school has started and it's fall, so do a google search and see what you can find near you!
