Hi is your item still for sale?
 yes I still have it for sale are you interested?
Very much, I think it is the perfect fit. The price is just a little bit too high for me.
Well I think the price is pretty fair because it's still very new and did not get much use at all so it's in perfect condition and it's priced much lower than new ones.
Could you maybe lower it to $540? 
Well how about 550 and I throw in the extra bracket?
