Unlucky mate, i've found Saturdays can be a bit hit or miss.
I've had some good results on Saturdays and other times hardly anyones home.
This is why I think the leaflet first thing is a waste of time, lets face it 99% either have a windie or dont want one. Its our job to find the 1% that do so its too much mucking about leafleting a whole estate and then going back and canvassing when the chances are you wont get anything anyway.
Personally I just get out cold calling, works for me
