good thing about leaflets is they rake in work for months even yrs afterwards. i did doorknocking and got good results but fliers worked for me quicker . its like kebab leaflets,iv got at least 3 in a drawer somewhere, dig them out every few months and thats what its about,the long haul.
a good idea that i keep thinkin of but havnt actually done, might be to put on yer flier that you do a monthly draw for a ten pound note , that way a lot of folk will keep the leaflet to hand , and cherish it
