The entertainment books are frequent fundraisers for local schools and charities. I complained about "having" to buy one last year for $25.00 but have saved much much more (lets see 3 nights at PGH X $150...) Now I can't wait for the new ones to come out when school starts. In addition to the hotel discounts we have enjoyed trying out local restaurants with the buy one get one free deals and we have used a number of the fast food coupons, Subway, Popeye's etc. I have learned to keep mine in the car, that way if we are out we have the coupons with us. There are coupoms for some things, and other discounts (like the buy one get one free) where you have to have your car. When we checked in at PBH they took my card and went to "verify" that it was valid. The current cards expire Nov. 1, so be sure your card is valid for the dates when you are checking in, not when you make the reservation.
