Amazon has another new feature for Prime members and this one helps members discover great children’s books. Starting this week, users can enjoy Prime Book Box, a subscription service that delivers curated children’s books every 1, 2, or 3 months. The new service is available to all U.S. Prime members and covers interests from baby to tween.

Initially introduced to customers in May by invitation only, the expanded service is a convenient way for families to have the love of reading delivered, with each box offering a selection of hardcover children’s books hand-picked by Amazon’s team of book editors. At just $22.99 per box, U.S. Prime members save up to 35% off List Price with Prime Book Box, providing the best value on books sold by Amazon. Prime Members can visit to learn more and sign up for their first box.

Amazon stated that Prime Book Box is ideal for readers from baby to 12 years old. To get started on the service, Prime Members simply answer a few questions about the little reader’s preferences, and you’d like a box every 1, 2, or 3 months. Then a team of book editors read thousands of books every year to find selections for Prime Book Box that your reader will enjoy again and again. The selections include new releases, classics, and hidden gems all tailored to your reader’s age.

You can always preview and customize the books from a list of curated options, or let your books be a surprise.

“As a mom who’s spent over 20 years reading and reviewing children’s books, the best part of my job is sharing a love of reading with kids and their families,” said Seira Wilson, Senior Editor, Amazon Books. “Over the past few months, it’s been both exciting and rewarding to hear that Prime Book Box is encouraging kids to spend more time reading. Now that Prime Book Box is available to all U.S. Prime members, I hope we can inspire even more children to discover a love of reading that will last a lifetime.”

Prime Book Box is available now for U.S. Prime members at just $22.99 per box.
