-Kids resale shops: This is probably my least favorite, as they tend to be on the "pricier" side of the lot, which still isn't pricey considering you'll probably pay around $2.00 per book.
-Kids resale events: Most places have kids resale events a couple times per year. These tend to have a large selection and decent prices. Some events even have a half-price day. Just Between Friends (with locations almost everywhere) usually puts on a good one. You can find other consignment shops & sales using Consignment Mommies or Kids Consignment Sales.
-Moms groups: If you belong to a mom's group or have a group of moms that meet up every once in a while, why not organize a children's book swap within your group? Tell members to bring 5 or so books that their kids no longer want or read, and everyone can go home with 5 new ones.
-Libraries: Most libraries have a "used book store" where they place books that they no longer need in circulation. I've seen prices range from $0.25 - $1.00 per book.
-Goodwill / Savers / any other thrift store: These places are great because they tend to have a large selection for a very inexpensive price, with most around $0.25-$1.00 per book.
-Garage / Estate Sales: Another great place to find children's books. Most people sell them for $0.10 - $1.00 per book, and most sellers will bargain with you if you ask!
Where do you buy your children's books?
