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!

Buyer: Hi can you tell me a little about the bike you are selling?
Seller: It's a vintage, one of a kind. We actually had it assembled by hand with performance parts, it's definitely a special bike for enthusiats. 
Buyer: My son would love this bike! Are you willing to come down on the price at all?
Seller: I'm willing to negotiate, but I don't have too much wiggle room on it.
Buyer: I would like to offer $300, how do you feel about that?
Seller: Can you meet me halfway on the price? $330 and I'll even throw in the spare tire I have for it.
Buyer: At the price of $330 could you drop it off at my house for me?
Seller: Sure, as long as you're local.

Seller: Hello
Buyer: Hello, I seen the AD for your iphone 7 and I love it. It's just what I've been looking for and unlocked with 128gb is unreal. 
Seller: Yes, I'm starting at $595 for it. 
Buyer: Yes, I seen that. Can you tell me a little more about the phone? any dings or scratches? Does it come with a case?
Seller: There's some very minor scratches on the back, but otherwise it's pristine. It also comes with Apple's warranty if you happen to have any issues down the line. No case included, I'm afraid. 
Buyer: Sounds like a great deal, unfortunately I'm on a tight budget. Will you happen to take $416 for the phone?
Seller: I'm sorry, I'm not taking less than $500 for this.
Buyer: Hmm, how about $480 if I come out now and pay in cash? I know you said no less then $500 but I really love that phone! 
Seller: I can live with that. $480 it is. 
Seller: 
Buyer: Awesome!
