Had a chap few weeks back ask me to do his windows as "last one was unreliable" ... 9 windows with med to large conny .. HE TOLD ME 10 quid or not to do them :
Told him £12 .... as 10 quid to low
Forget it he said as last one was charging 8 quid ... tried to tell him that was too low and his old windie was putting him to bottom of list hence "unrealiable"
so went on my way and his missus rang me a few days later and told me to start doing them at 12quid .... said sorry too busy ........ he would have dropped me as soon as he found a cheaper quote.
Stick to your pricing - dont be a busy fool
