I have recently phoned various window companies for a quote to replace a window with french doors. The exact window width is 1240 mms. I have one quote for €2500 from a well known window company. I then had a quote from a smaller local company for €1950, the same salesman however said that I would be cheaper just buying the windows from the company and he would get the fitter to fit in his free time on a Saturday as a nixer and that he would phone back with a new price which should be significantly cheaper than €1950. He phoned me back with a quote of €1900, just 50 euro cheaper than original quote saying that he underquoted to start with. I have since had another quote of €1800 from another company. Should I play them off each other or should I steer clear of this salesman. I know of work done by all three companies and all have had no complaints but i want the best price too but I am annoyed that this salesman expects me to go with a nixer for a reduction of fifty quid. What should I do next?
