Children’s books and Cluster Tutoring are a winning combination. On Saturday and Sunday, May 6 and 7, you can buy some great kids’ books and help Cluster at the same time.

Magic Tree Bookstore, 141 N. Oak Park Ave., will donate 20 percent of the cost of all books purchased on those two days to Cluster. Buyers must present the flyer below.

Magic Tree has been an Oak Park institution since 1984. It was named the area’s best children’s bookstore in Chicago Magazine. It features adult and YA titles as well as children’s books and also offers a wide selection of foreign language books, cards, toys, games, puzzles, and other fun accessories.

And here’s something new: For the first time, tutors will be allowed to purchase a book and give it to their students. So drop by Magic Tree on those days and stock up on some good reading material.
