I still buy one. But, they are not as good since a lot of places do coupons instead thru living social and groupon. For the DC one -- you pick whether you want the DC/MD book or the DC/VA book.
Ours used to have great coupons for Safeway, AMC theatres and a bunch of good restaurants. Now, there are very few restaurants listed for DC, most of them are in MD (we bought MD/DC). The good thing is the car rental deals are still better in most cases than what you find on hotwire. Same is true for sending flowers.
I'm really cheap, but I travel a lot and eat out a lot. So, I scope out deals everywhere.
