Q: Seller: Hey there, you're interested in my nice bike?
Buyer: I like that bike, but am on a budget. Not sure if you are negotiating today?
Seller: I am always negotiating, my friend. I'd like to make back the cost of the bike, so the bottom floor is 2100. What's your budget?
Buyer: What I am working with today is $1250, is there anything wrong with the bike, how old is it?
Seller: It's about 5 months old, I build bikes as a side hobby. To be fair the bike would cost 5000 retail, which means 1250 isn't really approachable unfortunately.
Buyer: I know, well would you consider 1800 if can give you cash by tomorrow, and pick it up?
Seller: 
Buyer:
