I've always used until recently Blue print on white paper looks a little sharper, Normaly get the expected 2-3% return but the great thing about leaflets is that they get every-were
I get calls from an area that was leafleted over a year ago,calls from friends and relitives of people that have had a leaflet, and the other week a call from a large stately home (now a bussiness centre)because some one had passed a leaflet onto them (got the bussiness).
As I've now got a nice sign written van I've been toying with the idea over recent weeks of doing a AA style promotion on a supermarket car park, complete with pain of glass and demonstrations, the more I think about it the more I think it could be a winner?
