Just to say something positive...they are a whole new thing for dogs to pee on and spend lots of time sniffing to see who else has been there. I bet they absorb a LOT of pee, too, as long as they get inside the bag of course.
JJ85, Aside from the fact that it is utterly wasteful there are many more reasons why these circulars are a bane to many of us who live here. It would be simple if all you have to deal with were just yours but not all neighbors are responsible and you are often left picking up bags of litter (loose flyers) that blow all over your block after these are distributed. The phone books off end up soggy messes on the streets. There is also a security angle: For those who take the time to stop their mail and suspend paper deliver to their homes while they are out of town, the Plum package folks often ignore this and pile their publications at your doorsteps thereby negating your intent to not call attention that you are out of town. I believe there was a lawsuit about this.
