Am I reading this right.
You have an A6 300Gm leaflet, One side extolls your service as a window cleaner. The other side has a logo or something on it which is an indication they want a quote which they display in their window.
So day 1 you drop say 300 in a a small area. day two you trawl the same streets again looking
for those who want a quote? thereby doing away with the " go away" Pill when canvassing?
