and also the fact that some people will pay up to 10 times the monthly value.but to be honest every round thats up for sale all have good paying customers and theres loads of scope and the window cleaners selling the rounds are always being asked to do extra like fascia cleans and conny roof cleans which brings in loads and loads of extra money. yes all good paying customers who pay by cash or cheque on the day as they never ever go out, they just sit there waiting for the window cleaner.Too true And don't forget there's new customers being added to the round all the time.So if you buy their window round it could have the potential to make you a MIL-YON-AIRE and it only takes 1 man 2 days a month!!! hope this helps
