Seller: Great bike, excellent condition, yours for $300!
Buyer: Hi. I am interested in this bike. May I ask how tall it is?
Seller: The seat reaches roughly 35 inches high.
Buyer: Ok. I was thinking of getting a bike like this for my son. How low would you go on the price?
Seller: If you can come pick it up today, I'd do $290. I think your son would love it!
Buyer: I think he would too. Could you go as low as $210? I am on a budget.
Seller: That's a little lower than I'd like to go. The bike has very few miles on it and is almost like new. Similar bikes sell for almost $400, I'm only asking $300 because I need the money. How about $285? That's fifteen dollars lower than I really wanted to go.
Buyer: I can come up to $275.
Seller: How about we split the difference at $280 and your son can be riding this amazing bike within the hour!
