Not the company, but leaflets in the paper, usually 1 of many, and many local freebies go straight in the bin.
I know its expensive, but solo distribution (your leaflet on its own) is the best way to go, but usually costs from £40 per 1,000.
Mine are always 2 sided, windows one side and upvc/conservatories the other, so a 2 or 3 connie cleans pays for the leaflets!!!!
