Yes i have read it Danny, good thread.
This is one of the reasons maybe when we quote a tenner , some snap your hands off , and others look at you in disgust, and tells you her neighbours pay 3 or 4 pound
(funny how she dont use him though

)
but with these price fluctuations , the customer will always shop around for the cheapest, until she realises who is the best !
Mind you ,i have watched one or two of these guys, .... blade down the glass and go,
nothing else.
