PROBLEM: Seller: Hey, how's it going? I take it you are interested in the bike?
Buyer: Hi, it's going good. And with you? Yes, I am interested in the bike.
Seller: I'm doing good! Let me tell you this bike is a decked out Santa Cruz Chameleon Custom. You can come take it for a ride and I guarantee you will fall in love with it.
Buyer: I would like that, it is a bit of a drive for me. Can you tell me, has this bike ever been in an accident? Any marks or scratches?
Seller: Never crashed it and no marks at all. It's only about 3 months old. I'm looking to sell it for $850
Buyer: Can you tell me, are the extra set of street tires new? How much tread is on them both?
Seller: The tires on the bike are in great condition. The extra set was only used for about a week so they are basically new.
Buyer: How long have you owned the bike?
Seller: 3 months.
Buyer: Are you the first owner? I am very interested in the bike.
Seller: I'm the only owner!
Buyer: Okay, great! Are you willing to come down on the price some? I am serious about buying this bike. However, like I said, it is a bit of a drive for me to come and get it.
Seller: Well, these bikes retail for $2,200 and I'm throwing in an extra set of tires. I think that the asking price of $850 is a steal. 
Buyer: That is a bit steep considering the travel it involves to come and buy it. I am serious with cash in hand.
Seller: If you have the $850 and are ready to buy, I will bring it to your doorstep.
Buyer: Could you do $750?
Seller: I could but I'd have to take out the extra set of street tires.
Buyer: How about $790 with the extra set of street tires included?
Seller: You got yourself a deal.

PROBLEM: Seller: Hello
Buyer: Hi I am inquiring about the iPhone.  I have an Android and am thinking of switching
Seller: Yeah, I don't blame you. Android is clunky. Well, you have come to the right place. This is an iPhone 5S 16GB that is in excellent condition. It has the original box and charger. It also has a screen protector already on it. I am asking for $160
Buyer: Wow that sounds like a good deal. Can you go a little lower as I just got my first paycheck and I only have 145
Seller: I understand what it's like. Keep in mind that this has a new Verizon 4G LTE sim card already installed as well. I'll even throw in a brand new case (never used still in box) for $160
Buyer: Ok I guess I can ask my husband for the extra dollars as it comes with extras. You got a deal
