Hi. I am interested in getting this bike for my kid
It is a great bike I am sure your kid would love it.  I just replaced the tires and had a complete tune up done.  I am only asking $175 and it is all yours.
Well it is still used. I have $150 cash on me if you'll accept that.
I just put quite a bit of money into it and was really looking to get 175 but how about we meet in the middle and say 160?
I'll throw in the 7 bucks in my pocket and buy it for $157 and I'll come pick it up. Sound good?
alright I can do that.
