Well, it does cost a little; Only $10 to join the National Arbor Day Foundation. But when you consider that they send you ten trees that they garantee will grow or they will replace them and they cover shipping them to you, come on, even at ten dollars to join that is a good deal. Plus you will get all kinds of educational material for your homeschool.
