Hello! I hear you'd like to purchase my bike.
yes, but $900 is to high, I would like to pay $828 for it
I purchased it for a good bit more, so I don't think I can go that low. How about $870?
It is still a bit high, how about $20 less for the amount of $850
It really is a great bike, hardly been used, wonderful city bike. Will you do $860?
Okay I will take it for $860
