I buy one or two Happenings coupon books each year. This year, I paid $20 to buy one from a local elementary school as part of a fund-raiser. You also can buy one online for $20 at http://www.entertainment-savings-offers.com/. Are they worth the cost? It depends. In years past, I have saved more than the purchase price of a book in discounts on hotel rooms alone. I also used several retail and two-for-one restaurant coupons, totaling more than the purchase price. If you spend much time in another city, such as the summer months, it may also pay to buy one for that city or state as well.
