Buyer: How are the tires on this?
Seller: The tires are great.  My wife only used this bike for 3 months before she switched to a hybrid.  The whole bike is in fabulous condition.
Buyer: Oh wow. So there are no problems with it at all?
Seller: None.  I am only selling it because we have enough bikes around our place and need some space.
Buyer: That makes sense well I have $50 cash on me and a giftcard for $10 to the mall I'd like to offer you
Seller: I'm not a mall guy at all, and $50 is pretty cheap for such an amazing ride.  I'm willing to go $75.  How does that sound to you?
Buyer: If you can throw in a helmet you've got a deal. 
Seller: I can do that!  You know women--my wife bought a brand new helmet to go with her new bike, so we have a practically new one we can throw in no problem.  You've got yourself a deal.

Seller: Hi, how are you today?
Buyer: Hello very well and youself?
Seller: Good. Do you have any questions? I am asking $1900, which is a great deal on this place.
Buyer: yes is the apartment big in size?
Seller: Well it is big for a studio.. but still a studio apartment.
Buyer: That's great I see its perfect for students! I would definitely want that. I am a student myself, but my budget doesn't fit in with the price. What can we do?
Seller: Well I can come down slightly to $1750. Or another option for the full $1900 is it coming furnished.
Buyer: Great I can do the 1750! works great for me! Thanks

Seller: Hey there are you interested in my Polk Audio 5.1 Home Theater System w/ Onkyo Receiver, cherry? its in great condition.
Buyer: What is the lowest you can go?
Seller: I can part ways with it for about $350 if you can come and pick it up from my place and everything. Does that sound like a fair deal? the original asking price is $100 higher than that.
Buyer: I can pick it up but the best I can do is $300
Seller: I really can't go any lower than $350. Its got all of its original items included, and is in excellent condition without a scratch, in the original boxes, with all the original manuals.
