we use labelled envelopes so they can send us a cheque - however we've had a few not wanting to play the game, one woman in particular told us it was OUR job to come around and collect the money, thats how its always been done - I got on the phone to her and explained about time taken to collect etc but she was having none of it, not sure whether to dump her or just let it build up and collect once every 3/4 months.
