HI, Are you interested in my beautiful bike?
I am very interested in your bike but the price is a tad high for me
Well I'm asking 350 because the bike is hand made in Italy, has very little wear, it folds so you can take it on the bus or in a car + it is beautiful!  What would you offer me for it?
280
Make it 300, you pick it up and we have a deal.
300 sounds great
