Get any of the following books for free, plus $1 shipping per book. My books arrived in about 10 days.
World Book Expert Explorers (grades 6-8): Excite their curiosity and demanding mind. This option allows kids ages 11-13 to explore history’s greatest myths and mysteries through topics like Jupiter and the Asteroids, Searching for Atlantis and more.
World Book New Explorers (grades K-2): Explore the big world with your little learner. This option covers topics like Animal Babies, Earth’s Features, Nature’s Patterns, World of Pets and more.
World Book Junior Explorers (my fave)
World Book Junior Explorers (ages 6-8): Ignite your child’s interest in science and math. This option gives your child an engaging introduction to elementary math and science with topics like Addition, Energy, Force & Motion, The Circulatory System and more.
World Book Series for kids: pick one or get all three.
Your best bet is to order all three free books. You’ll pay $3 total, and should you wish to discontinue, you can take care of ending all three subscriptions in one call to 1-888-215-4327 (note: you’ll have to cancel within 2 weeks from when you receive your order). I cancelled New Explorers and Expert Explorers and kept Junior Explorers.
