The guy from crystal I can't remember what the start price was around the 4K mark I think (just for a front door) the conversation went like this
Him - this week only tho we can take that to 3k are you interested?
Me - No
Him - ok if you allow us to stick a board at the front of your property for 4 weeks we can knock £500 more off interested?
Me - No
Him - oh I also forgot you get a recycling discount of your old front door that's another £250 off interested?
Me - No
Him - ok I can see you want a good deal let me make the call to my manager who can give special offers on top of all the above...
Ring ring ring.... he chats to someone
Him - ok very good news my manager says I can add a special manager discount today only which is £400 but that's bending his arm, interested?
Me - No, please leave
Him - hang on let me ring him again he doesn't like to lose a customer
Ring ring ring.... chatting again
Him - ok he said he can change that £400 to £500 but that is a rock bottom price and the best deal possible EVER... interested?
Me - when I called crystal I made it clear I wanted just a quote so I will take the price you said and think about it
Him - no no no no if you don't take this here and now you will not get this price it's a one time only, if I have to come back it won't ever be this cheap again.
Me - bye
Him - repeats pretty much everything he has said previously
Me - bye
Him - shall I give you 5 mins to think about it before you sign?
Me - bye, walking towards door
Him - so we have a deal you want it?
Me - bye push him out door slam door.
