Ex Input:
Buyer: Hi, I have an iPhone 6 I need unlocked. Are you able to provide that service?
Seller: yes I sure can, my team and I specialize in these kind of things. We leave all of our customers satisfied with our service. 
Buyer: If aafter you unlock it and I happen to experience a problem do you provide a warranty to fix the problem for free?
Seller: In case there is any problem, I will take a look and see what I can do without any additional cost. Also in the event that there is a problem that I can't fix, I will gladly refund you 
Buyer: Would you be willing to accept $35 for a first time customer. If I'm satisfied I will be able to refer a lot of my friends to you and help you earn more business.
Seller: We usually cut a deal for our first time customers but we normally don't accept any lower than $40
Buyer: I think $40 is very fair.

Ex Input:
Seller: Hello
Buyer: Hi I'm interested in buying your bike today. 
Seller: Great I'm interested in selling! This bike is fully loaded with everything an off road enthusiast would want.
Buyer: The only thing is the price it's a bit much. Could you come down? I'd be willing to offer 100 bucks for it  
Seller: I paid 500 for it last year. The list price really is just about as low as I can go.
Buyer: 125 is the best I can offer. My car just broke down so I'm looking for a commuting bike. 
Seller: I've got an extra tire I can throw in, but I'm sorry the lowest I can go is 200
Buyer: Would you do 175 if I can come pick it up?
Buyer: 
Seller:

Ex Input:
Buyer: Hello. Are you still selling the bike? 
Seller: I've had a few offers, but I'm willing to see what you have to say
Buyer: How old is the bike and what kind of condition is it in?
Seller: It's a vintage, so it has a great personality!  Haha it's actually in great condition, I was never really able to use it much
Buyer: Okay and it has also been repainted right? 
Seller: Yes, I got it professionally done
Buyer: That's good but with the original paint it would be worth more. Would you sell it for 140? 
Seller: That's pretty low.  Even sanded down, this bike is worth 190.  Lowest I can go is 200 with what I put into it already (mods and painting)
Buyer: Modifying it actually decreases the value too, customizing something makes it worth less you don't just add on the cost of custom parts. That takes away any value it had as a vintage item. 
Seller: Hmm, well it sounds like you probably aren't interested then.  As a non-vintage bike, it's worth 200.  The vintage should add on to it.  Lowest I'll go is 180 if you pick it up.
Seller:
