1. Why Large-Print Word Search Books Dominate Repeat Sales
Unlike a non-fiction book that a reader buys once, avid puzzle fans finish a 100-page word search or sudoku book every two weeks and immediately buy the next volume in the series.
By theming your puzzle series around hobbies that older adults love—National Parks, 1960s & 1970s Nostalgia, Cozy Gardening, Classic Cinema, or World Travel—you build a loyal customer base that buys Volume 1, Volume 2, and Volume 3.
