When selling books during certain times of the year or holidays, you can use seasonal trends and reader interests to optimize your assortment. For example, during the winter months and holidays, books related to coziness and the holiday atmosphere sell well, such as Christmas novels, cookbooks with holiday recipes, or books about winter adventures. Summer, on the other hand, should emphasize light and entertaining works such as adventure novels, thrillers, or books for beach reading. In spring and fall, you can offer books on personal growth, motivational topics, or even books on gardening. If you want to tailor your book offerings to seasonal trends as much as possible, you can use the online service https://booksrun.com/books/sell which not only allows you to buy and sell books, but also to rent them out.
