[Q]: Seller: Hello, are you interested in this bike?
Buyer: Hello, I am interested in the bike.
Seller: Do you have any questions about it?
Buyer: It seems like it's in great shape, but are there any issues with it that aren't listed? I am on a budget on what I can spend so I need a good deal please :)
Seller: None, at all. Like I posted it's all custom built and if you have issues you can bring it in and we'll fix it for you. 
Buyer: Okay, sounds good. I would like to offer 485 for the bike. I know it may sell new higher, but even though it's a great bike, it's still used so more likely to have some issues pop up sooner.
Seller: Yes, not going to be able to do it at that price. The parts cost more than that. 
Buyer: Well, as I really am on a budget, I can go up to 532, but that is really the most I can pay for the bike. I just can't afford a higher price.
Seller: The lowest I can go is 600.
Buyer: Let's meet in the middle at 550 and that would work out well for both of us.
Seller: Ok that works for me. Thank-you.

[Q]: Seller: Hello. How can I help you?
Buyer: Hi, I am interested in the apartment
Seller: Sure. Do you have any questions?
Buyer: Is it available any sooner than the 10th?
Seller: No sorry its not available sooner
Buyer: How close is it to town? 
Seller: Its in town and in a very convenient location with everything around the corner
Buyer: does it come furnished?
Seller: Yes it does
Buyer: the price is a little out of my range, I'm willing to pay $2480
Seller: I am sorry but 2480 is very low for what you are getting back. There is a pool, fitness center, clubhouse, and lots of stuff that you're getting with it. I can give it to you for $2700 nothing lower than that
Buyer: Ok, that sounds fair
Buyer: 
Seller: Great then we have a deal! Thanks for choosing us!
