There are thousands of books on the theme of Hallowe'en. The best time to buy them is a day or two after the event when they go on sale for half price. Be sure to go out and browse your local bookstores in a few days and then pack these books away for next year. Also these "smart shopping" books would make a great gift for someone next year.
