They claim that they will 'target' an area for you, but they don't give a monkey's where they deliver, they still charge the same, so your fliers could be posted into a few hundred individual council flats, dozens of tiny terraces etc. It's too haphazard for me, I prefer to deliver them myself (actually, it's the wife who does the leaflet distribution :

) so we know exactly where they go and they don't get wasted.
Might work on a country delivery, I suppose because it can be very time consuming walking up and down half mile drives
